NFE/NFL/NFA Series

LC low-pass filters (EMIFIL, LC combined filters, EMI filters) are a combination of a capacitor and inductor. This means they can provide steeper insertion loss characteristics than when used separately. Therefore, it becomes possible to suppress noise while minimizing the effect on the signal waveform in high-speed signal lines even when the signal and noise frequencies are close. Moreover, these filters also contribute to a reduction in mounting space because they are combined products.

Type and Appearance	萝莉影视Status	Applications	Features
Large Current Type	In Production	For power lines	This is a high-performance chip EMIFIL that combines a feedthrough capacitor and ferrite beads. It can handle large currents and has outstanding high-frequency characteristics thanks to the feedthrough capacitor.
Single Type	NRND	For signal lines	NFL series is compact size EMI suppression filter of 1.6×0.8×0.6mm. It has steep and deep insertion loss characteristics with T-type circuit. This product has large insertion loss in wide frequency range, results to good noise suppression effect.
Array Type	NRND	For signal lines	NFA series is LC combined noise suppression filter whose noise suppression curve is very steep and deep. Four circuits are built in the chip size, it saves the large amount of mounting space.
