EMI
Suppression Filter
NFW31S's steep attenuation
characteristic means excellent EMI
suppression without waveform
cornering.
3-terminal capacitors suppress
signal frequencies as EMI
frequencies so the signal waveform
is distorted.
Combinations of inductors and
capacitors can yield a steep
attenuation characteristic, but they
require a great deal more mounting
space.
Moreover, at high frequencies the
EMI suppression is less than that
obtained by NFW31S.
