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.
