FEATURES
鈥?With a size of 2.0脳1.0 mm, this compact thin-film common mode
filter features two circuits.
鈥?We have succeeded in reducing its thickness to 0.8 mm.
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.
