*1: Mesurement frequency of inductance : at 100kHz. 1V
*2: ( )is typical value.
*3: DC superimposition : It indicates the D.C. current value when inductance value become more than 65% of the nominal one.
*4: The temperature rise : The value of D.C. current when temperature rise is ∆t=40°C (Ta=20°C).
