PCMFxUSB3B/C series

Common-mode EMI filter for differential channels with

integrated bidirectional ESD protection

Rev. 2 — 29 January 2019

Product data sheet

1. General description

Common-mode ElectroMagnetic Interference (EMI) filters with integrated bidirectional 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 ±20 kV on each signal line.
