    With ten discrete component functions integrated on one chip, a dual ESD/EMI audio filter enables high audio quality in stereo headsets, mobile phones, portable multimedia players, PDAs and notebook computers. The audio filter (model CA04F2FT5AAUD010G) effectively reduces parasitic noise and increases audio quality. It features low series resistance and combines EMI filtering and ESD protection in a EIA-0405, two-fold array package. With a cut-off frequency of 20 MHz and low serial resistance of 0.2 ?, this component is useful in applications requiring low bandpass attenuation. At frequencies from 200 MHz to 4 GHZ, the attenuation is higher than -20 dB for all quad-band GSM (850/890/1800 MHz) and UMTS standards (2.1 GHz), as well as for GPRS/WLAN and Bluetooth (2.4 GHZ). At 900 MHz, it offers very high attenuation of more than -60 dB. The design of the EPCOS ESD/EMI audio filter also enables excellent ESD protection for sensitive ICs (IEC 61000-4-2, level 4 standards). Its internal structure provides a double-clamping function and is therefore able to reduce the ESD pulses from 8 kV to 70 V. The component footprint is 1.37 x 1.0 mm2. Max. DC operating voltage is 5.5 V and typical insertion loss is -20 to -60 dB. Pricing is $0.15 each in lots of 10,000 with delivery in eight to 12 weeks. EPCOS, Iselin, NJ. (800) 888-7728.
