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.
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.
