specifications are subject to change without notice. 320 general description continual advances in digital ic technology are creating stringent demands on emi/rfi levels in equipment. emi/rfi low pass filters are required in personal computers, data terminals, test equipment and process con- trollers for high frequency suppression into or out of elec- tronic equipment. filter selection and design considerations the roll-off frequency fc, defined as the frequency at which the filter passes one-half the power it receives at its input terminal, can be specified from the low megahertz range up to about 100mhz. this frequency, also known as the -3 db frequency, will be determined by the r and c values chosen. custom resistor and capacitor values are available to optimize system performance. the specification of these values will depend on con- straints relating to noise frequencies, system performance and driver loading. the following procedure is suggested to choose appropriate values of r and c. the first step is to determine the desired roll-off frequency of the filter, which will lie between the signal frequency and the dominant frequencies of the emi/rfi noise. by determining the pole of the filter (setting the denominator of the transfer function equal to zero), the roll-off frequency can be expressed in terms of r and c: f c = r s + r l + 2r 2 p c(r + r s )(r + r l ) furthermore, the rc combination must be chosen so that the additional rc time delay will not result in exceeding the sampling window of the receiving ic, due to excessive lengthening of signal rise and fall times. rise time from 10% to 90% of the waveform amplitude can be calculated in terms of the circuits rc time constant using the 1 Cexp (Ct/rc) relationship for a charging capacitor. at 10%, t l = 0.1 time constants, and at 90%, t h = 2.3 time constants. time constant equals r th c, where r th is the thevenin-equivalent resistance as seen by the capacitor. therefore, equating the difference in the two times to the maximum tolerable rise (or fall) time: t max = t h - t l = 2.2r th c t max = 2.2 (r + r s )(r + r l )c r s + r l + 2r a final consideration is the insertion loss. as mentioned previously, the voltage drop across the two resistors will attenuate the voltage reaching the load. normally, logic high and low levels will still be within valid limits. the signal attenuation can be minimized by choosing small r values rel- ative to the load impedance. typical values for r range from 10 to 50 ohms. bourns low-pass filters for emi/rfi suppression no. of lines bourns p/n package 7 4118r-601-rc/cc 8 4120r-601-rc/cc dip 8 4420p-601-rc/cc wide body smd rc r cc c 250 25 500 50pf 270 27 101 100pf 470 47 181 180pf 820 82 201 200pf 101 100 standard resistance/capacitance values and codes application notes C emi/rfi filters 601 series
