DUST CHOKE COILS
CAT. No. E1008K
?MAJOR USES
@Output choke coils for Switching Mode Power Supply
@Choke coils for DC-DC converter
@Normal mode choke coils for noise control
@Choke coils for Power Factor Corrective circuit
?FEATURES
@Excellent characteristics in frequency and temperature
@Miniaturization and excellent D.C. bias characteristics in comparison with ferrite choke coils
by the feature of higher saturation magnetic fl ux density
?D.C. bias of Dust core (1) ?D.C. bias of Dust core (2)
