CM1412 - 2 Channel Headset Microphone EMI Filter

Description

The CM1412 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.

Features

  • Functionally and pin compatible with CMD’s CSPEMI202A OptiGuard™ coated for improved reliability at assembly Two channels of EMI filtering Pi-style EMI filters in a capacitor-resistor-capacitor (C-R-C) network Greater than 40dB attenuation at 1GHz +8kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge) +15kV ESD protection on each channel (HBM) Supports AC signals.
