AMORPHOUS CHOKE COILS
CAT. No. E1008E
The FM series coils are made of nano-crystal.
?MAJOR USES
@Common mode coils for noise filter in inverter or
large capacity power supply
?FEATURES
@Small profile, light through adoption of high permeability core
@High inductance in spite of a small number of turns
@Low temperature rise and, low D.C. resistance
@Stable frequency performance of noise suppression
in wide frequency range
@Excellent temperature characteristics
@Conforming to insulating type B and incombustibility UL94V-0
