Notes: (1) Rate current, ^I_rated, 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 device for 30 minutes.
(3) DC resistance is measured at 25°C.
