RE: resistor power rating
Posted by TimFox on May 20, 2012 at 13:18:36:
I am very conservative, after I once burned a finger on a power resistor running close to rating.
I usually derate by x4 from a "reasonable" power value, and by x2 if I am sure it is a worst-case or higher-than=possible power value.
