For each degree the ambient temperature is raised above 25°C, there is a reduction by 1% of the permitted overload.
The key characteristics table is only applicable to resistors suitably mounted on a heatsink with a thermal resistance of 1°C/W for 25 and 50W ratings, 0.7°C/W for 100W and 0.28°C/W for 250W ratings.
This data is only valid when thermal grease is used and the resistor is correctly tightened by mounting screws.
