(1) Inductance is measured at 100kHz, 0.1 Vac without DC current.
(2) The rated current (Irated) is the approximate current at which inductance will be decreased by 20% from its initial (zero DC) value.
(3) Heating Current is the DC current which causes the inductor temperature to increase by approximately 40°C.
(4) DC resistance is measured at 25°C.
