CM1412 2-Channel Headset / Microphone EMI Filter Array with ESD Protection Product Description The CM1412 is a dual, low−pass filter array integrating two pi−style filters (C−R−C) that reduce EMI/RFI emissions while 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 35 dB attenuation in the 800 to 2700 MHz range. These pi−style filters support bidirectional filtering that control EMI both to and from a microphone element. They also support AC signals, enabling audio signals to pass through without distortion. In addition, the CM1412 provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD).
