?MAJOR USES
@For noise filter in inverter or large capacity power supply
?FEATURES
@Small profile, light weight 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
