Power Derating Curve
Maximum load power should be reduced when operating in ambient environments above 70 C, as per the provided curve.
Rated Current Calculation
I = P/R, where I is rated current (A), P is rated power (W), and R is resistance (ohm). If calculated current exceeds the maximum working current for the type, the maximum working current is the limiting factor.
