What Rated Current?


Xmultiple's Engineering Department

Rated Current is the level of continuous DC current that can be passed through the inductor. The DC current is based on a maximum temperature rise of the inductor at the maximum rated ambient temperature. The rated current is related to the inductor's ability to minimize the power losses in the winding by having a low DC resistance. The rated current is part of the inductor's ability to dissipate this power loss in the windings.

Rated current can be increased by reducing the DC resistance or increasing the inductor size. Low frequency current waveforms the RMS current can be substituted for the DC rated current.
