CM1418 Description
The CM1418 is an L−C EMI filter array with ESD protection that integrates two Pi−filters (C−L−C) for a headset speaker. The CM1418 has ponent values of 117 pF/3.0 nH/117 pF. The parts include ESD protection diodes on all input/output pins, and provide a very high level of protection for sensitive electronic ponents against possible electrostatic discharge (ESD).
