RMS current ratings are power ratings for CODACA’s inductors, derived by applying DC or low frequency AC current to measure the resultant temperature rise. This allows for an accurate determination of temperature rise vs. RMS current, which can easily be related to temperature rise vs. power loss: Power Loss = Irms2 × DCR.

Meanwhile,CODACA’s inductor losses include skin effect, high-frequency core loss and proximity effect, which can add to the temperature rise. While these losses are dependents and should be verified in situations, CODACA offers design tools for predicting frequency effects. To estimate core loss, conductor loss, and temperature rise of ours power inductors, use the Power Inductor Loss Comparison.
