EMI Filters

KNF Series

Features

• Distributed constant type LC filter.

Prevents ringing caused by circuit

impedance.

Suitable for high speed digital circuits and

video signal lines.

• Stable noise attenuation over wide

frequency ranges.

• Low profile (T=0.95mm max.) suitable for

miniature electronic equipments.

• First class auto-placement
