FEATURES
鈥?This compact thin-film common mode filter has with a size of
L1.25脳W1.0mm.
鈥?We have succeeded in reducing its thickness to 0.6mm.
鈥?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.
鈥?This product contains no lead and supports lead-free soldering.
