ETC2 CMF21T-121M-N2 Smd multilayer common mode filter Datasheet

SMD Multilayer Common Mode Filter - CMF Series
CMF Series
The CMF series is a type of common mode filter designed and produced
using the multilayer technology. The multilayer construction allows for
excellent noise suppression for signal lines used in high-speed and
high-density digital equipment such as personal computers, facsimiles,
DSC, STB, etc. Both standard series and custom-design products are
available.
Features
Applications
 Multilayer construction for effective suppression of common mode
 High speed interfaces (IEEE1394, USB2.0, and LVDS) in electronic
noise at high frequency
devices
 Excellent solderability
 PDP, LCD TV, DVD player, PC, Audio player, DSC
 Compact design
 Digital audio and video equipment such as PDAs, DVC, CD player,
MD player, etc.
