CM1418 Overview
California Micro Devices’ CM1418 is an L-C EMI filter array with ESD protection, which integrates two Pifilters (C-L-C) for the headset speaker. The CM1418 has ponent values of 117pF-3.0nH-117pF. The parts include ESD protection diodes on all input/output pins, which provide a very high level of protection for sensitive electronic ponents that may be subjected to electrostatic discharge (ESD).
