On-Board Type (DC) EMI Suppression Filters (EMIFILr)

Chip EMIFILr LC Combined Monolithic Type NFL18ST/NFL18SP/NFL21S Series

NFL18ST Series

The NFL18ST series is an EMI suppression filter for

high speed signal lines, achieving T-type structure in

1.6x0.8mm size with Murata's multilayer technology.

s Features

1. Ultra-small size in 1.6x0.8x0.8mm

2. Steep insertion loss characteristics realize

excellent noise suppression and prevent distortion

of signal waveform.

3. By minimizing stray capacitance of inductor,

achieves high performance in noise suppression

in high frequency range.

4. Five different values of cut off frequency are

available, ranging from 100MHz up to 500MHz.

5. No polarity using the same structure on all the

side electrode.

s Applications

Noise suppression for video signal lines (RGB lines)

and high speed clock lines
