AMORPHOUS CHOKE COILS
AMORPHOUS CHOKE COILS
Upgrade!
The FM series coils are made of nano-crystal.
?MAJOR USES
@Common mode coils for noise filter in inverter or
large capacity power supply
D2
?FEATURES
Maximum outer diameter : D1(Vertical), D2(Horizontal)
@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
Maximum width : W
Total lead length* : L=15mm(+5mm, -5mm)
Soldering boundary* : a=1.5mmMAX
*The bottom of the core or coil ( ) is defined
as base surface.
@Excellent temperature characteristics
@Conforming to insulating type B and incombustibility UL94V-0
