PCMFxUSB3S series

Common-mode EMI filter for differential channels with

integrated ESD protection

Rev. 3 — 7 March 2019

Product data sheet

1. General description

Common-mode ElectroMagnetic Interference (EMI) filters with integrated ElectroStatic Discharge

(ESD) protection for one, two and three differential channels. The devices are designed to provide

low insertion loss for differential high-speed signals on each channel while unwanted common-

mode signals are attenuated.

Each differential channel incorporates two signal lines that are coupled by integrated coils. Diodes

provide protection to downstream components from ESD voltages up to ±15 kV on each signal line.
