PERCENT OF RATED POWER
KRL Precision Wirewound Resistor Derating Curve
PC and K Series resistors must be derated for tolerances below 0.1%, and for elevated ambient temperatures. Use the curve for the desired tolerance, and, knowing the maximum ambient temperature expected during use, determine the maximum allowed percentage of rated power from the graph.
