(1). Inductance tolerance±20% tested at 0.25V, 0ADC and 25℃
(2). DCR measured at 25℃.
(3). The DC current at which the inductance decreases by 25% from its initial value (10uH-18uH) or 20% from its initial value (22uH-820uH).
(4). The DC current that results in a 40℃ temperature rise from 25℃ ambient.
