CMF2012F Series
Common Mode SMD Filter for Signal Line
FEATURES
• This common mode filter is characterized by its
small sized
• Highly effective in noise suppression. High
common-mode impedance at noise band and low
differential-mode impedance at signal band.
• Due to the low differential-mode impedance with
high coupling factor, there is almost no distortion
PRODUCT IDENTIFICATION
on high speed signal.
• This series is micro-produced by auto machines
for its huge productivity and accuracy with
all-day CCD inspection.
