C31E8.pdf 02.9.5 On-Board Type (DC) EMI Suppression Filters (EMIFILr) Chip EMIFILr LC Combined Winding Type NFW31S Series 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 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. 2.30.2 1.80.2 3.20.3 1.60.2 (1) (2) (3) (1) : Input electrode (2) : Ground electrode (3) : Output electrode 0.70.3 0.650.2 0.70.3 s Features 9 1. The filters suppress signal noise with little or no attenuation of the signal itself. 2. Murata's original internal structure design enables excellent noise suppression up to high frequencies (40dB at 1GHz typ.). 3. The NFW31S series is available in six different values of cutoff frequency ranging from 10MHz up to 500MHz.
