Murata, NFW31S, Signal Filter, 25 V dc, 200mA, SMD, 3.2 x 1.6 x 1.8mm / 7257461

1206 EMIFIL® (LC Combined) Wire Wound Type NFW31S Series. NFW31S series high performance signal line chip EMI filters 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, making these chips effective in applications where the signal and noise frequencies are close to each other. Suppresses signal noise with little or no attenuation of the signal itself Murata's original internal structure design enables excellent noise suppression up to high frequencies (40dB at 1GHz typ.)
