Notes:
(1) Rate 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.
