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 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.
