Product Name : CMF (common mode filter) for USB 3.0 or higher speed interface’s GHz noise suppression

Model : CMF


Compact Common-Mode Filter(CMF)
 

FEATURE & APPLICATIONS
CMF-2012 is ceramic multi-layer common-mode filter and developed for high speed differential signal interfaces such as HDMI, USB3.0, SATA 3.0, or Thunderbolt.
The cut-off frequency of CMF-2012 for differential mode is above 8 GHz and therefore high-speed differential signal integrity is not degraded.
The common-mode noise is reduced about 32 dB at 2.45 GHz, which covers WiFi frequency band.
EMI/RFI common mode noise suppression on High-speed differential interface, such as HDMI, USB 3.0, SATA 3.0, Thunderbolt etc.
