Notes:
(1) Rated current, I rated , is the approximate DC current at which inductance will be decreased by 20% from its initial (zero DC) value or the current at which
? T = 50 ° C, whichever is lower.
(2) I sat is the saturation current at which inductance rolls off approximately 30% from its initial value.
(3) DC resistance is measured at 25 ° C.
