Product Description

The CM1402 is an EMI filter array with ESD protection, which integrates three pi filters (C-R-C) and two additional channels of ESD protection. The CM1402 has component values of 20pF-47Ω-20pF, and 20pF-100Ω-20pF. The parts include avalanche-type ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD).
