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.
