(1) Inductance is measured at 100kHz, 0.1Vrms, 0Adc.
(2)
The rated current is the approximate DC current at which ∆T is approximately 60°C. This current is determined by soldering
the unit on a typical application PCB, and then applying the current to the unit for 30 minutes.
(3) Isat is the saturation current at which inductance rolls off approximately 30% from its initial unbias inductance value.
