※1: Inductance Measuring frequency : 2.5μH ～ 9.2μH at 7.96MHz; 10μH ～ 82μH at 2.52MHz;100μH ～ 47 mH
at 1 kHz
※2: Saturation current: The DC current at which the inductance decreases to 90% of it’s initial value.
※3: Temperature rise current: The DC current at which the temperature rise is △t＝20℃.(Ta＝20℃).
