Description
The ECMF2-40A100N6 and ECMF4-40A100N10 are highly integrated common
mode filters designed to suppress EMI/RFI common mode noise on high speed
differential serial buses like HDMI 2.1, HDMI 2.0, HDMI1.4, USB4, USB 3.2 Gen 2,
USB 2.0, ethernet, MIPI, Display Port and other high speed serial interfaces.
They have a very large differential bandwidth to comply with these standards and can
also protect and filter one or two differential lanes.
