I have had a good rummage about and can't find anything definitive.
Ther are two key parameters to every resistor. Power and resistance.
From those you can derive maximum voltage that can be applied to the resistor should
so that it doesn't burn out.
I am given to understand that there is some relationship between power rating and
physical dimensions. It's to do with heat dissipation.
Does anyone know of a chart or a list that details the standard dimensions of metal film resistors
as they relate to power ratings.
I would expect a 2W 50 ohm resistor to be bigger than a 0.25W one for example.
I have hundreds of mf resistors. Just need a way to categorize them power wise.
Thanks.
