Notes :

(1) The heating current is the DC current which causes the component temperature to increase by approximately 50°C.

This current is determined by soldering the component on a typical application PCB, and then applying the current to the device for 30 minutes.

(2) The saturation current (Isat) is the approximate current at which the inductance will be decreased by 20% typical from its initial (zero DC) value.

(3) The saturation current (Isat) of HM72A-124R7LF, HM72A-124R7HLF and HM72A-12100HLF is the approximate current at which the inductance will be decreased by 30% typical from its initial

(zero DC) value.
