The signal line chip EMI filter NFW31S series consists
of high performance EMI suppression filters. They are
designed for noise suppression in high speed signal
digital circuits in which the signal harmonics are
prone to becoming noise sources. These filters achieve
a 100dB/dec. (typ.) damping characteristic with
Murata's innovative circuit design. This makes these
chips effective in applications where the signal and
noise frequencies are close to each other.
1. Suppresses signal noise with little or no
2. Murata's original internal structure design enables
3. NFW31S series is available in 9 different values of
