Key Characteristics
Overload duration RCH25 RCH50 BDS100 BDS250
1 sec. 375W 750W 200W 1500W
2 sec. 300W 600W 150W 1250W
5 sec. 125W 250W 125W 1000W
10 sec. 75W 150W 100W 750W
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.
