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