The PCMFxUSB3S series are common-mode EMI filters with integrated ESD protection for differential channels. They are designed to attenuate unwanted common-mode signals while providing low insertion loss for high-speed differential signals. Each channel consists of two signal lines coupled by integrated coils, and diodes offer ESD protection up to 15 kV on each signal line. These filters are available for one, two, or three differential channels and come in compact WLCSP packages.
