When run at its rated power?
I'm referring to 1/4 - 10 watt resistors in TVs and PC power supplies,
probably in 30-50 Celcius surrounding air.
I thought that resistors were supposed to be chosen for twice the
actual power, but I've seen many 0.5W to 1.0W resistors run at almost
exactly their rated power continuously.
How long is a piece of string? I think you need to rethink what you're
asking.
What additional information should I specify, other than rated power,
actual power, and ambient temperature? I'm not dropping high
voltages.
