Notes : (1) Inductance is measured at 100kHz, 0.1Vrms, 0Adc.
(2) When leads connected in parallel, DCR is half the value. When lead connected in series, DCR is twice the value
(3) Isatcurrentisthesaturationcurrentatwhichinductancerollsoffapproximately30%fromitsinitial(zeroDC)value.
(4) IrmsequalsDCcurrent,thatcausescomponenttoincreasebyapproximately 40°Cfrom25°Cambient.
(5) Iratedcurrentistheratedcurrentatwhichinductancerollsoffapproximately10%fromitsinitial(zeroDC)value.
