D DC current (mA)
(1). Inductance tolerance for 1.0uH: ± 30%, for 1.4uH~68uH: ± 20%. Tested at 0.25V, 0ADC and 25 ℃
(2). DCR measured at 25 ℃ .
(3). The DC current at which the inductance decreases by 10% from its initial value.
(4). The DC current that results in a 40 ℃ temperature rise from 25 ℃ ambient.
