Derating
Ambient Temperature: Operating temperature range of -55°C to +350°C.
Higher temperatures require derating as illustrated.
Stability: Resistance chance is 1/2 or less than that of conventional power resistors when operated at the
same wattage.
Characteristic U
1. 275°C maximum hotspot temperature.
2. 5% maximum âR for 2000 hour load life.
Characteristic U:
1. 350°C maximum hotspot temperature.
2. 3% maximum âR for 2000 hour load life.
