Description
500
The NFW31S's steep attenuation
characteristic means excellent EMI
suppression without waveform
cornering.
500
3-terminal capacitors suppress
signal frequencies as EMI
frequencies so the signal waveform
is distorted.
500
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 the NFW31S.
