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. In...
