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. SHAPES AND DIMENSIONS CIRCUIT DIAGRAM RECOMMENDED PC BOARD PATTERN
