DC superimposition : It indicates the D.C. current value when inductance value become more than 65% of the nominal one. The temperature rise : The value of D.C. current when temperature rise is ∆t=40˚C (Ta=20˚C). ✽This specification might be changed without notice due to under developing and improving.
