PCMFx EMI Filters with ESD Protection Nexperia PCMFx CMF EMI Filters with ESD Protection deliver integrated bidirectional electrostatic discharge (ESD) protection of up to ±20kV for one, two, and three differential channels. These common-mode EMI filters are designed to provide low insertion loss for differential high-speed signals on each channel. The series provides superior RF performance and common-mode suppression over a wide frequency range. Nexperia PCMFx CMF EMI Filters exhibit high symmetry between line pairs and are available in WLCSP5, WLCSP10, and WLCSP15 packages for a small footprint. Applications include smartphones, cell phones, and cordless phones, as well as derive applications in camera serial interfaces (CSI) and display serial interfaces (DSI).
