(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 component for 30 minutes.
(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.
