Dual ESD/EMI Audio Filter Integrates 10 Discrete Component Functions
With 10 discrete component functions integrated on one chip, the EPCOS ESD/EMI audio filter (CA04F2FT5AAUD010G) reduces parasitic noise and increases audio quality in portable devices. The filter features low series resistance, comes in a 405, two-fold array package, a cut-off frequency of 20 MHz and low serial resistance of 0.2 Ohms, making it appropriate where low bandpass attenuation is required. At frequencies from 200 MHz to 4 GHZ, the attenuation is higher that -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 high attenuation of more than -60 dB.
