Resistor Getting Really Hot at Herlinda Broady blog

Resistor Getting Really Hot. Dig out a datasheet for the resistor and see how hot it is expected to get if you actually were to have it dissipate 1/4 w. Resistors get hot because excess energy is dissipated in the form of heat when current flows through the resistors. The derating curve means that if you run in a 70c ambient temperature (air around the resistor) you can use 100% of the rates power (5w) but if. Typically a 3w cermaic resistor is reated to something like a 200c or more surface. It's unlikely that resistors will suffer significant damage without other components that you are soldering suffering far more. Exceeding a resistor’s power rating causes more current to flow through the resistor. The reason that a resistor gets too hot is that you are putting more power into it than it can dissipate at a reasonable temperature.
