Ambient Temperature (°C)

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 ∆R for 2000 hour load life.

Characteristic U:

1. 350°C maximum hotspot temperature.

2. 3% maximum ∆R for 2000 hour load life.
