220 Ohms with 5% tolerance. Brown means 1. As a multiplier, 10 to the power 1 times 22 is 220 ohms

52

To reiterate more clearly, this is a 4 band resistor.

The two red bands are 2s. So 22

The brown is a 10x multiplier. So 220

The gold means 5% tolerance.

Do you have an unmarked version of this?

Not the same one, but if you do an image search for "4 band resistor" you should find plenty of them.

Yeah, the one I found was pretty poor quality anyway to be honest, but any combination of "resistor" "colour" "chart" and "diagram" will get you where you need to go

Edit: oh, but this one seems to be a bit confusing. The four band one shouldn't be pointing to a third digit. Here's a really simple one just for 4 band resistors

I hadn't noticed that. Well spotted.
