LinkCom Manufacturing Co.,Ltd
Common Mode SMD Filter for Signal Line
CMF Series CMF1210U
Features:
Small size.
Highly effective in noise suppression.
High common-mode impedance at noise band and low differential-mode impedance at signal band.
Virtually no distortion on high speed signal.
Adopted high precision micro-production technology, quality is ensured by all day CCD inspection.
This series is in compliance with RoHS Directive, Halogen free, and compatible with lead-free solders.
Operating temperature: -25°C ~ 85°C.
Applications:
Noise countermeasure for any electronic devices such as personal computer and peripheral equipment, Universal
Serial Bus(USB), amusement equipment (IEEE 1394), LCD panels (LVDS), etc.
