Electrical Characteristics

※1. Inductance measuring condition : Inductance≦10μH at 100kHz,1V; Inductance>10μH at 1kHz,1V.

※2. Saturation current: The DC current at which the inductance decreases to 90% of its initial value.

※3. Temperature rise current: The DC current at which the temperature rise is △T＝40℃.(Ta＝20℃)
