AMORPHOUS CHOKE COILS
AMORPHOUS CHOKE COILS
?MAJOR USES
@Choke coils for DC-DC converter
@Output choke coils for Switching Mode Power Supply
?FEATURES
@Minimum device thickness of 6.8 mm with high D.C. rated current
@Remarkably small of D.C. resistance in this type of device
@Use of Fe-base amorphous for excellent operation stability at high temperature
@Preparation of both SMD and SIP type
