" High-speed signal application EMIFILr are high perfor-
mance EMI suppression filters which increase the slope
of insertion loss frequency characteristic curves (shape
factor), thereby improving noise and signal separation.
These are used for high speed signal applications in
which noise and signal frequency approach the same
value.
To avoid the elimination of both the noise and specific
signal components, 3-terminal capacitors and other
components are applied.
An NFW31S with a built-in capacitor and an inductor type
BLM--B are available.
BLM18HD has additional performance for suppressing
GHz range noise after cut off frequency.
" The EMIFILr with waveform distortion suppressing func-
tion suppresses waveform distortion caused by the reso-
nance of digital ICs and surrounding circuits.
