Any of y'all know what's going on with this resistor? Brown black gold gold black is a bit unusual. From what I've found I'm pretty sure it's a 1 ohm resistor (±5%), but I'm unsure about that last black band. From what I've found, it's either the temp. coefficient, the reliability, or it's telling me it's a wirewound resistor. Given this is a generic 5V power supply, I *think* it's the last one, but can anyone confirm?

This discussion of a similar resistor

eevblog.com/forum/projects/is-

refers to it as a "fusible resistor", which will not catch fire when it blows. You might see if that would make sense in the design, and also look for other independent confirmation.

@ed_packet That would seem to make sense, and would explain why it's spot on the pcb is marked "FR1". Thank you!

@auravulpes

You're welcome. My secret search weapon for finding this was looking for the exact phrase "brown black gold gold black", finding mostly forum postings, and not finding it listed in any of the easy to find resistor decoder charts.

If you happen to blow that one, it appears that Digikey has several vendors that have "fusible through hole resistors", like this listing only by way of example
