CSPEMI201AG
2 Channel Headset Speaker EMI Filter with ESD Protection
Product Description The CSPEMI201AG 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 speaker port on a cellular telephone or similar device. Each high quality filter provides more than 35 dB attenuation in the 800−2700 MHz range. These pi−style filters support bidirectional filtering, controlling EMI both to and from a speaker element. They also support bipolar signals with a cutoff frequency of 31 MHz, enabling audio signals to pass through without distortion.
