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.
