CSPEMI202FCTAG

EMI Filter with ESD Protection, Headset Microphone 2CH Audio Filter

The CSPEMI202AG is a dual low-pass filter array integrating two pi-style filters C-R-C that reduce EMI/RFI emissions while at the same time providing ESD protection. This part is custom designed to interface with a microphone port on a cellular telephone or similar device. Each high quality filter provides more than 35dB attenuation in the 800-2700 MHz range. These pi-style filters support bidirectional filtering, controlling EMI both to and from a microphone element. They also support bipolar signals, enabling audio signals to pass through without distortion.
