Component Identification

[ANavetta]

This component is from an older programmable power supply, and that first black stripe is throwing me off.
Any thoughts?

I'm going to mention this because I've been sucker-punched before by it.
When resistors over-heat, those painted colors can change on you.
Looks like Black, Red, Black, Silver, Orange to me,. but having been fooled before, I don't bet on them anymore.
Can you get an ohmmeter reading across it? It'll be a low-value reading.
Do you know what it came out of to get the actual value from a schematic?

Unfortunately I do not have a schematic and there does not appear to be one readily available online
. I do think you are correct on the color bands. The part that makes me a little uneasy is that it is 5 bands, and the first is black. Do I just read that as 0.2 Ohms 1% on the 4 band code and ignore the first 0. Not something I have encountered before.

Thank you.

As said above ... the first band may not be black
I have never in 50 yrs of electronics seen a resistor with a black first band. It's more likely to be a heat discoloured brown band

Judging by the wire that's used to form the resistive part it's going to be sub-1Ω.

WHERE in the circuit did this part come from?

What is the make/model of the PSU anyway? Someone may know the whereabouts of or even have a schematic.

It looks like it's gotten very hot, but maybe not so hot as to make it go open circuit.

If it is open circuit you may be able to expose a part of the wire near the middle of the resistor and measure the resistance to one end (and double it).
