Overview
The ECMF04-4HSWM10 is a highly integrated common mode filter designed by STMicroelectronics to suppress EMI/RFI common mode noise on high-speed differential serial buses. This component is particularly suited for high-speed serial interfaces such as HDMI Full HD, MIPI, USB 2.0, USB 3.2 Gen 1, and Display Port. It offers robust ESD protection and is packaged in a compact QFN-10L package, making it ideal for space-constrained applications.
