ECMF02-2AMX6 and ECMF04-4AMX12 Common Mode Filters

STMicroelectronics - 2 and 4 lines common mode filter with integrated ESD protection

Image of STMicroelectronics' ECMF02-2AMX6 and ECMF04-4AMX12 Common Mode FiltersSTMicroelectronics' ECMF02-2AMX6 and the ECMF04-4AMX12 are highly integrated common mode filters designed to suppress EMI/RFI common mode noise on high speed differential serial buses like HDMI, MIPI D-PHY, MDDI or USB 2.0.

The ECMF02-2AMX6 can protect and filter one differential lane, while the ECMF04-4AMX12 can protect and filter two differential lanes.


  • Very large differential bandwidth > 6 GHz
  • High common mode attenuation:
    • -34 dB at 900 MHz
    • -20 dB between 800 MHz and 2.2 GHz
  • Very low PCB space consumption
  • Thin package: 0.55 mm max
  • High reduction of parasitic elements through integration
ST Advantage Applications
  • Integrated ESD protection (IEC61000-4-2 Level 4)
  • Lower clamping voltage
  • Small PCB area, save up to 80%
  • HDMI
  • MIPI
  • MDDI
  • USB2.0 HS
