â–  The FN 354 family of filters is intended primarily for applications that require ex- tremely effective interference suppression across a broad frequency spectrum.
â–  FN 354 are equally suitable for the oper- ation on star and delta power networks.
â–  Applications requiring high-frequency attenuation
â–  Industrial power supplies
â–  Medical equipment
â–  Advanced two-stage filter circuits with highly saturating resistant toroidal induc- tors, in conjunction with feedthrough capacitors on each of the three phases and the neutral line, ensure that these filters provide very high attenuation in the upper frequency band.
â–  Office and data processing equipment
