| oH V SC AV ER OM AI SIO PL LA N IA BL S NT E Features Lead free versions available RoHS compliant (lead free version)* New Product Development Integrated Passive Device RF Low Pass Filter Performance ESD Protection to IEC61000-4-2 Spec. *R 2FAD-C20R Series - Integrated Passive & Active Device using CSP General Information The 2FAD-C20R devices, manufactured using Thin Film On Silicon technology provide ESD protection and EMI filtering for the data port of portable electronic devices such as cell phones, modems and PDAs. The device incorporates six low pass filter channels. Each channel has a series 100 ohm resistor assuring a minimum of -30 dB attenuation from 800 MHz to 3 GHz. The device is suitable for EMI filtering of GSM, CDMA, W-CDMA, WLAN and Bluetooth frequencies. Each external port of the six channels includes a back-toback 6.5 Volt Zener diode for ESD protection. Two additional standalone 6.5 Volt Zener diodes are available for ESD protection on power lines or USB data ports. The ESD protection provided by the component enables an eight line data port to withstand a minimum 8 KV Contact / 15 KV Air Discharge when tested according to the ESD method specified in IEC 61000-4-2. The device measures 2.04 mm x 2.64 mm and is available in a 20 pin (4 x 5 array) CSP package intended to be mounted directly onto an FR4 printed circuit board. The CSP device meets typical thermal cycle and bend test specifications without the use of an underfill material.

The IEC 61000-4-2 test method will be adapted for component level testing. The device will provide the specified ESD protection performance on the "EXT1 - EXT8" pins only. 2. "Let Through" is a measure of the component of an incident ESD transient that the protection device allows through to the downstream circuitry. *RoHS Directive 2002/95/EC Jan 27 2003 including Annex Specifications are subject to change without notice. Customers should verify actual device performance in their specific applications. 2FAD-C20R Series - Integrated Passive & Active Device using CSP Mechanical Characteristics This is a Silicon-based device and is packaged using chip scale packaging technology. Solder bumps, formed on the Silicon die, provide the interconnect medium from die to PCB. The bumps are arranged on the die in a regular grid formation. The grid pitch is 0.5 mm and the dimensions for the CSP packaged device are shown in Fig. 2 below. 858 40 (33.78 1.57) 248.5 45 (9.78 1.78) BUMP A1/PIN 1 INDICATOR BOURNS LOGO A1 B1 C1 D1 A2 B2 C2 D2 500 (19.69) A3 B3 300 DIA.

"Package level" testing of the integrity of the solder joint is carried out on an independent Daisy-Chain test device. A 25-Pin Daisy Chain component is available from Bourns for this purpose. (Part No: 2TAD-C25R) This is a 5 x 5 array, featuring 0.5 mm pitch solder bumps. The Distance to Neutral Point (DNP) on that component is larger than that of the 2FAD-C20R and is thus deemed a worse case for Thermal Cycle testing. "Silicon level" reliability performance will be assured by similarity to other integrated passive CSP devices from Bourns. Individual Channel Schematic This section contains the schematic (See Fig. 3 below) for the single channel in the integrated passive device. Note that the electrical parameters of primary interest are (a) DC Resistance (b) ESD performance and (c) low pass filter attenuation. In terms of DC parameters it should be noted that all resistor values have a tolerance of 10 %. This schematic consists of a series 100 ohm resistance and two Back to Back Zener 6.5 Volt diodes for ESD protection.
