(2) The rated current is the approximate DC current at which ΔT 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. * Low cost version General Note TT Electronics reserves the right to make changes in product specification without notice or liability.
