High-speed common-mode EMI filter offers integrated ESD protection

The ECMF4-40A100N10 from STMicroelectronics provides highly effective noise suppression for high-speed interfaces such as USB Type-C® ports. The integration of ESD protection helps to save board space and reduce parasitic effects. 

STMicroelectronics has introduced the ECMF4-40A100N10 integrated common-mode filter to enable the suppression of EMI or RF interference on high-speed differential serial buses. 

High-speed interface technologies for which this filter can provide protection include: 

  • HDMI v2.1 and earlier
  • USB4
  • USB 3.x 
  • USB 2.0
  • Ethernet
  • MIPI
  • DisplayPort 

By integrating noise suppression and ESD protection functions into a single device, the ECMF4-40A100N10 helps designers to keep the effect of parasitic capacitance and inductance to a minimum. 

The filter can protect and filter one or two differential lanes. It is supplied in a compact 10-lead QFN package measuring 1.4 mm x 2.2 mm x 0.5 mm.
