Is it common for resistors to burn out? How long do they usually last before they go bad?

I have never had one come back, did you you use it on an alarm?

and was it 1/2 watt 5% or a 1/4 watt?

Yes, it was used on an alarm. It is a 1/2 watt. I was just curious of their reliablity and life span. I don't have one that has gone bad, I was just curious as to whether I should put it so that it can be accessed easily in case it does go out.

Suggestion number one: Read up on ohm's law https://www.the12volt.com/ohm/ohmslaw.asp .

I've a feeling that you've exceeded the max current capacity and it'll burnup again. What are you using this resistor for? Connected to what circuit and feeding it how?

Prepare your future. It wasn't the lack of stones that killed the stone age.

I am using it to bypass an anti theft system. I have not burned one up, i was just wondering about how long they last?
