(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. inductance heating (2) 100 khz 100 khz, 0.1 v current part @ 0 adc @ i rated i rated (1) (adc) dcr (3) dim d. dim.e number h 10% h min. h typ.
