(1) The rated current is the approximate current at which inductance will be decreased by 20% from its initial (zero DC) value.
(2) 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 apply the current to the
component for 30 minutes.
(3) Isat is the saturation current at which inductance rolls off approximately 30% from its initial unbias inductance value.
(4) PC Board layout, proximity of other components, trace size and airflow will affect temperature rise and must be considered
when selecting an inductor.
