MURATA entered the suppression filter field at an early stage in response to serious problems stemming from electromagnetic interference between electronic equipment. These pioneering efforts in the filter field resulted in the development and world-wide marketing of the EMI Suppression Filter (EMIFIL(R)). In 1979, MURATA successfully developed an on-board type EMIFIL(R), thereby realizing a solution to PC board noise suppression. In 1985, the EMIFIL(R) class of on-board filters ware further developed to produce a chip-based EMI suppression filter, thus substantially improving noise suppression in compact electronic equipment. Based on more than thirty years of ceramic dielectric and ferrite technology experience, MURATA's full range of high-performance EMIFIL(R) serve to overcome and control all types of electronic-equipment noise problems. Further, MURATA's various noise suppression circuits, designed for the diversified needs of the electronic industry, offer great advantages in the pursuit of noisefree equipment, etc. Currently, MURATA is completing a system for the analy-sis and solution of noise problems. For the finest in noise suppression components, boards, and related equipment contact the nearest MURATA sales office.
!ABOUT OPERATING CONDITION
Noise suppression levels resulting from MURATA's EMI suppression filters (EMIFIL(R)) may vary, depending on the circuits and ICs used, type of noise, mounting pattern, lead wire length, mounting location, and other operating conditions. Be sure to check and confirm, in advance, the noise suppression effect of each filter, in actual circuit, etc., before applying the filter in a commercial-purpose equipment design. EMIFIL(R) for both DC and AC power supplies, and thru-type EMI suppression filters for high-frequency equipment (thru-type EMIFIL(R)) are available.

Typical Application of EMI Suppression Filter (EMIFIL(R)) for DC line
The main applications of EMIFIL(R) for DC lines are as follows: Descriptions of these applications are based on standard digital PC board. Typical applications of EMIFIL(R) in PC boards can be divided into four types: 1. Elimination of non desirable harmonics in high speed signal lines
High speed clock signals, for example, contain higher level harmonic components, which can cause noise. These higher harmonics are reduced to within acceptable range by EMIFIL(R). For relatively low noise levels, chip ferrite bead inductors and chip solid EMIFIL(R) (3-terminal capacitors) are used; for high level noise applications, signal line EMIFIL(R) are used.
1 2 3 4 5
3. Noise suppression in I/O cables
Some I/O cables, when connected to PC boards, act as an excellent antenna, which can radiate noise and induce noise through coupling. To prevent this, EMIFIL (R) are used at the connection point between the I/O cable and PC board to prevent noise from being introduced into the board. For relatively low level noise suppression, chip ferrite bead inductors are used; for high noise suppression, chip solid EMIFIL(R) (3-terminal capacitors) are used. At high speed signal line connection points, signal line EMIFIL(R) are used.
2. Elimination of noise in DC power supplies
DC power supplies utilize high frequency current in converting AC power to DC power, etc., and these currents may cause noise. Since DC power supplies are designed to supply only DC current, the current flow is larger than that on the signal lines, which can cause DC resistance. Therefore, in such situations, EMIFIL(R) having a wider noise suppression band and larger current capacity are used. For relatively low noise suppression, chip ferrite bead inductors and chip solid EMIFIL(R) (3-terminal capacitors) are used; block-type, DC power supply EMIFIL(R) are used to suppress higher level noise.
4. High voltage surge countermeasures
EMIGUARD(R) filters, which also have a surge absorbing function (using a varistor), are effective in preventing both higher harmonic noise and high voltage surges (such as electrostatic discharges) from interfering with PC board operation.

" High-speed signal application EMIFIL(R) are high performance EMI suppression filters which increase the slope of insertion loss frequency characteristic curves (shape factor), thereby improving noise and signal separation. These are used for high speed signal applications in which noise and signal frequency approach the same value. To avoid the elimination of both the noise and specific signal components, 3-terminal capacitors and other components are applied. An NFM51R with a built-in capacitor and an inductor type BLM--B are available. BLM11HB has additional performance for suppressing GHz range noise after cut off frequency. " The EMIFIL(R) with waveform distortion suppressing function suppresses waveform distortion caused by the resonance of digital ICs and surrounding circuits.
" These choke coils reduce common mode noise, which causes problems on balanced transmission lines, and are effective against common mode noise in the several MHz to several 100 MHz frequency range. They are ideally suited for use on DC power supply lines and interface cables. " There are two types of chip common mode choke coils: the high-performance wound wire PLM250.

" EMIGUARD(R) eliminates both surge noises and EMI noises due to its dielectric varistor material. " Effective when high frequency noise and high voltage surge suppression are required, and also in situations when surging starts at extremely high speeds. This type of surging cannot be eliminated with general type varistors. " VFM41R is chip type of EMIGUARD(R). Construction of EMIGUARD(R) (DSS710)
" Block type EMIFIL(R) are resin encased, built-in, high performance EMI suppression filters, which use a feed-thru capacitor having excellent high frequency characteristics. " Used when the noise frequency is high, or when extreme countermeasures are required. " The BNP filter series features high performance filters, which are used to suppress noise with frequencies greater than several megahertz in signal circuits. With a current capacity of up to 10A, however, this filter can also be used in DC power circuits (available with 2 or 3 circuits per block). " The high performance EMIFIL(R) BNX series exhibits significant noise suppression effects over a wide frequency band (extending from 100kHz to 1GHz) in DC power lines.

Chip Ferrite Bead BLM Series
Essential for Noise Suppression in High Speed Signal Lines and DC Power Lines
The chip ferrite bead BLM series comprises ferrite bead inductors in the shape of a chip. This inductor generates a high impedance which at high frequencies mainly consists of a resistance element. The BLM series is effective in circuits without stable ground lines because the BLM series does not need a connection to ground. Chip sizes of 1.0Z0.5, 1.6Z0.8, 2.0Z1.25, 3.2Z1.6 and 4.5Z1.6mm are cataloged. (The BLA series of array type chip ferrite bead is also cataloged.) The nickel barrier structure of the external electrodes provides excellent solder heat resistance. Both flow and reflow soldering methods can be employed.
!FEATURES
The BLM series comprises, the R series (for digital interface), the A series (for standard), the B series (for high speed signal), and the P series (for large current). 1. BLM--R series-For Digital Interface The BLM-R series can be used in Digital Interface. Resistance of BLM-R series especially grows in the lower frequency range. Therefore BLM-R series is less effect for digital signal waveform at low frequency range and can suppress the ringing. 2. BLM--A series-For Standard The BLM-A series generates an impedance from the relatively low frequencies. Therefore the BLM-A series is effective in noise suppression in the wide frequency range (30MHz-Several hundred MHz). 3. BLM--B series-For High Speed Signal The BLM-B series can minimize attenuation of the signal waveform due to its sharp impedance characteristics. Various impedances are available to match signal frequency 4. BLM--P series-For Large Current The BLM-P series can be used in high current circuits due to its low DC resistance. It can match power lines to a maximum of 6A DC (BLM41P).

(At Maximum Signal Frequency insertion loss is 6dB in 50 impedance circuit.) marked items are designed for ultra-high speed signal lines such as next generation memory interface. Since these impedance curve rise from several hundred MHz, these items can suppressnoise unless the misoperation of circuits. (At Maximum Signal Frequency, impedance is 22 which is used as Dumping.)

Chip Ferrite Beads For GHz Range Noise Suppression BLM11H Series
High Impedance at 1GHz Provides Excellent Noise Suppression on Interface of High Speed Application
With the rapid growth of high-speed CPUs, high-speed graphics and telecommunication equipment, the demand for high frequency components has greatly increased. Murata recognizes this demand and has provided the BLM11Hseries as a timely and ideal solution. The BLM11H- series has a modified internal electrode structure, that minimizes stray capacitance and increases the effective frequency range. Impedance values of 1000 can be attained at frequencies of GHz and greater.
!DIMENSIONS
0.4T0.2 0.8T0.15 1.6T0.15 0.8T0.15
!FEATURES
1. The BLM11H- is similar to the conventional BLM at frequencies, below 100MHz, however at 1GHz the impedance is appox. 3 times larger. 2. The BLM11HA is intended for standard signal lines as this series provides significant impedance across a broad frequency range. The BLM11HB provides a sharper rolloff after the cut off frequency, therefore this series is ideal for high speed signal lines. 3. The magnetic shielded structure minimizes cross talk.

Chip EMIFIL(R) for Signal Line NFM51R Series
100dB/dec. (typ.) Damping Characteristics for High Speed Signal Line
The signal line chip EMIFL(R) NFM51R series consist of high performance EMI suppression filters. They are designed for noise suppression in high speed digital circuits in which the signal harmonics are prone to becoming noise sources. These filters achieve a 100dB/dec. (typ.) damping characteristic made possible by Murata's innovative circuit design. This makes these chips effective in applications where the signal and noise frequencies are close to each other.
!FEATURES
1. The filters suppress signal noise with little or no attenuation of the signal itself. 2. Murata's original internal structure design enables excellent noise suppression up to high frequencies (40dB at 1GHz typ.). 3. The NFM51R series is available in six different values of cutoff frequency ranging from 10MHz up to 500MHz.

Notice of Chip EMIFIL(R)/Chip Varistor
! CAUTION 1. Rated Current/Rated Voltage/Operating Temperature
Don't use products beyond the rated current, the rated voltage and the operating temperature range, or, a fire may result due to the deterioration of the insulation resistance, excessive heat, etc.
!NOTICE 1. Standard Land Pattern Dimensions
The capacitor type chip EMI suppression filters (NFM/NFA series) suppress noise by conducting the high-frequency noise element to ground. Therefore,to obtain maximum performance from these filters,the ground pattern should be made as large as possible during the PCB design stage. As shown below,one side of the PCB is used for chip mounting,and the other is used for grounding. Small diameter feedthrough holes are then used to connect the grounds on each side of the PCB. This reduces the highfrequency impedance of the grounding and maximizes the filter's performance.
1 2 3 4 5
2. Mounting Density
Give special attention when mounting products close to other product that radiate heat. The excessive heat by other products may cause deterioration of insulation resistance and excessive heat at this product, resulting in the fire.

Notice of Chip EMIFIL(R)/Chip Varistor
2. Solder Paste Printing and Adhesive Application
When reflow soldering the chip EMI suppression filter,/Chip varistor, the printing must be conducted in accordance with the following cream solder printing conditions. If too much solder is applied, the chip will prone to be damaged by mechanical and thermal stress from the PCB and may crack. In contrast, if too little solder is applied, there is the potential that the termination strength will be insufficient, creating the potential for detachment. Standard land dimensions should be used for resist and copper foil patterns. When flow soldering the EMI suppression filter/Chip Varistor, apply the adhesive in accordance with the following conditions. If too much adhesive is applied, then it may overflow into the land or termination areas and yield poor solderability. In contrast, if insufficient adhesive is applied, or if the adhesive is not sufficiently hardened, then the chip may become detached during flow soldering.

EMI SUPPRESSION FILTERS
EMIGUARD(R) VFR303/DSS706/DSS710 Series
3-Terminal varistor-capacitor EMI filter. Enables simultaneous EMI suppression and surge protection
The EMIGUARD(R) VFR303, DSS706, and DSS710 series EMI suppression filters incorporate capacitors that have a varistor function to enable simultaneous EMI noise suppression and surge protection functions. These varistor-enabled capacitors act not only as bypass capacitors against noise but also as surge protectors that route most of the surge current from high voltage power surges to ground to protect the circuits. Furthermore, the three-terminal structure provides excellent performance characteristics in the high-frequency range, making these filters effective against high-frequency noise and short rise-time surges which are difficult to combat with ordinary capacitors and varistors. The VFR303 series is for protecting semiconductor devices, the DSS706 series is for use on signal lines, and the DSS710 series is for use on power supply lines.

Method of using the BNP and BNX filter blocks, and applications.
!USING EMIFIL(R) EFFECTIVELY
The block type EMIFIL(R) effectively prevents unwanted reflections and external noise from entering the equipment circuitry and power lines by grounding all the high frequency components which make up the noise. Therefore, if grouding is improperly done, the filters may be unable to achieve the performance they are capable of. To prevent this, be sure to observe the following instructions. 1. When designing the P.C. board, use all the available grounding terminals, and arrange the grounding circuit so that the area of the foil for the grounding circuit is maximized. 2. Minimize the distance between the P.C. board ground and the filter's grounding plate. Use of through-hole P.C. boards. 3. Whichever P.C. board is used, push the filter into the P.C. board up to the terminal roots. 4. Do not connect PSG to CG by any other means except through the filter.

Noise Suppression Principles by DC EMIFIL(R)
" Function of DC EMI Suppression Filters
DC EMI suppression filters absorb and eliminate high frequency noise which may produce electromagnetic interference in PC board circuits. These filters are used in secondary circuits, and are small in size and light in weight, which further enhances their excellent noise suppression functions. Chip and adhesive type filters can be mounted on PC boards automatically. These filters are effective in the suppression of radiation noise in computers, peripheral equipment, and digital circuit application equipment (including various types of microcomputer application equipment), and function to suppress noise in audio/visual equipment, which uses digital memory chips and DSP. These filters are also effective for improving the noise immunity of equipment used in noisy environments (such as electronic equipment for automobiles).
1 2 3 4 5
" Capacitive Noise Suppression
When a capacitor is connected (bypass capacitor) to ground from a noisy signal line or power line, the circuit impedance decreases as the frequency increases. Since noise is a high frequency phenomenon, it flows to ground if a capacitor has been connected to ground, thereby making it possible to eliminate noise. (See Fig. B below.) EMI suppression filters employing a capacitor in this way are used to eliminate this type of noise.

" Noise Filter Suppression Principles
Generally, noise problems occur when the noise source and electronic equipment sensitive to the influence of noise are located in close proximity to one another. In such situations, as shown in Fig.A below, noise is conducted through a conductor, which produces an inductive field around the noise source. To overcome such noise problems, it is preferable to reduce the amount of noise generated by the noise source or improve the noise resistance of adjacent equipment. In order to satisfy equipment performance specifications and eliminate noise effectively at the same time, however, it is customary to reduce the amount of noise generated by the noise source, if it can't be eliminated altogether.

" High frequency Capacitor Characteristics Used for EMI Suppression Filters
Even general-purpose capacitors can be used for noise suppression. However, since noise has an extremely high frequency range, general-purpose capacitors may not function as effective bypass capacitors, due to the large residual inductance built into the capacitor. All the capacitors used in MURATA's EMI suppression filters employ a 3 terminal structure or thru-type structure, which functions effectively even at high frequencies, thereby minimizing the influence of residual inductance. Consequently, an effective filter circuit can be formed even at frequencies exceeding 1GHz. (Refer to Fig. C below.) (a) Construction of capacitor

" Configuration of EMI Suppression Filters (DC)
DC EMI suppression filters are used to suppress noise produced by conductors. Noise radiation can be suppressed, if it is eliminated with a filter in advance. Generally, such noise suppression is achieved with DC EMI suppression filters, according to the capacitive and inductive frequency characteristics of the respective conductors in the circuit. Filters of this kind can be roughly divided into those : (1) employing a capacitor, (2) employing an inductor, (3) employing a capacitor and inductor combination.

Noise Suppression Principles by DC EMIFIL(R)
" Inductive Noise Suppression
When an inductor is inserted in series in a noise producing circuit (See Fig.D), its impedance increases with frequency. In this configuration it is possible to attenuate and eliminate noise components (high frequency components). The MURATA EMI suppression filter functions in this way.
Noise
This type of filter is also effective in the suppression of highspeed signal circuit noise. When used in DC power circuits, capacitive-inductive filters prevent resonance from occurring in peripheral circuits, thus making it possible to achieve significant noise suppression under normal service conditions.

f :Frequency L : Capacitance Value Fig.D Inductive Noise Suppression
In addition to the capacitive-inductive filter, MURATA also has an EMI suppression filter (EMI-GUARD(R)) combining a capacitor with a varistor, useful for surge absorption; and a common mode choke coil effective, for common mode noise suppression. MURATA also has a range of built-in filter connectors which greatly reduce filter mounting space requirements.
" Characteristics of Inductors Used in EMI Suppression Filters
General-purpose inductors also function to suppress noise when configured in series with a noise producing circuit. However, when general-purpose inductors are used, resonance may result in peripheral circuits, signal wave forms may become distorted, and satisfactory impedance may not be obtained at noise frequencies (due to insufficient high frequency impedance characteristics). The inductors used for MURATA's EMI suppression filters are designed to function nearly as a resistor at noise frequencies, which greatly reduces the possibility of resonance and leaves signal wave forms undistorted. And since sufficient impedance is obtained for frequencies ranging to hundreds of MHz, these specifically designed inductors operate effectively to suppress high-frequency noise. (See Fig.E) Equivalent Circuit

" Expressing EMI Suppression Filter Effects
EMI Suppression Filter effects are expressed in terms of the insertion loss measured in the circuit, normally specified in MIL-STD 220A. As shown in the 50 impedance circuit in Fig.5 below, insertion loss is represented by the logarithmic ratio of the circuit output voltage with and without a filter in the circuit, which is multiplied by 20 and expressed in dB. Therefore, an insertion loss of 20dB indicates an out put voltage ratio (B/C) of 1/10, and an insertion loss of 40dB indicates an output voltage ratio (B/C) of 1/100.

" Capacitive-Inductive EMI Suppression Filters
If a capacitive and inductive suppression characteristics are combined, it is possible to configure a much higher performance filter. In signal circuit applications where this combination is applied, noise suppression effects which have little influence on the signal wave form become possible.
