(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.
