EMC Components

TCM Series TCM1210 Type

Common Mode Choke Coils for Signal Line

SMD

FEATURES

• This compact thin-film common mode filter has with a size of

L1.25

×W1.0mm.

• We have succeeded in reducing its thickness to 0.6mm.

• By providing wide bandwidth (cutoff frequency: 3GHz) for

differential mode transfers while maintaining common mode

impedance, this filter provides noise reduction and has almost

no effect on high-speed differential transfer line signals.

• This product contains no lead and supports lead-free soldering.

APPLICATIONS

For radiant noise reduction in electronics devices.

LVDS lines and IEEE1394 interfaces used in notebook PCs and

LCD monitors.
