✽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 65ꢀ of the nominal one.
✽4: 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. Thank you for your understanding.
