2.3±0.2 1.8±0.2 3.2±0.3 1.6±0.2 (1) (2) (3) (1) : Input electrode (2) : Ground electrode (3) : Output electrode 0.7±0.3 0.65±0.2 0.7±0.3 The signal line chip EMI filter NFW31S series consist of high performance EMI suppression filter. They are designed for noise suppression in high speed signal digital circuits in which the signal harmonics are prone to being 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.
