Common Mode Filters

Common Mode Filters
Product Name : Common Mode Filters
Product Description
CMF(Common Mode Filter)
that remove common mode noise at the differential mode communication side for data transfer lines like USB, HDMI, MIPI, MHL, Display Port, and camera.
CMF
is made by two coils surrounded by magnet materials. The design allows differential (differential mode) transmission signals to pass while eliminating common mode noise using the inductor’s power.
Product Introduction
characteristic
  1. Small size and tight dimensional tolerance     Size: 0605 (0.65x0.50x0.30)、0806 (0.85x0.65x0.40mm) Tolerance:+-0.05mm.
  2. High common mode impedance up to 90ohm (at 100MHz) is available and common mode impedance down to 7ohm(at 100 MHz) for super high speed appreciation like USB3.1.
  3. CMF series enables noise suppression for differential signal line without distortion in high-    speed signal transmission due to its line impedance matching.  
  4. High Cut-off Frequency.
Application

Common mode noise suppression of high  speed differential signal lines for MIPI, USB, IEEE1394, MHL, HDMI, LVDS, etc

Applicable in :
  1. NB, Desktop
  2. Smart phones
  3. Cameras, Camcorders
