EMI Filter with ESD Protection

Favorite

Overview

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). The ESD diodes connected to the filter ports are designed and characterized to safely dissipate ESD strikes of ±10 kV, beyond the maximum requirement of the IEC 61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±25 kV.
