EMI Filters

KNF Series

FEATURES

• Disturbed constant type LC filter. Prevents ringing

caused by circuit impedance. Suitable for high speed

digital circuits and visual line circuits.

• Stable noise attenuation over wide frequency ranges

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

electronic equipment

• First class auto-placement

APPLICATIONS

• PCs, laser printers, cellular phone, clock data lines for

LCD display

• High speed video signal circuits and interface circuits

• High speed digital circuits

• Anti-noise solution

Achieves effective noise suppression in noisy high

speed circuits without signal waveform distortion
