# Identification of 5 band Resistor from power supply

This Resistor is not functioning

The 4th band is Gold, I've read that means it's an exception.

The 3rd looks to me as silver, not gray, this is why I've added a picture.

I'd like to replace it, so I kindly ask what values should I look for in the replacement if I can purchase a resistor of a different value

The location is marked with R910

Edit: band 1: Red 2: Red 3: (left this empty) 4: Silver 5: Gold 6: Gray

The results from here:

https://www.1728.org/resisclr.htm

2.2 ohms 5 % tolerance 1 ppm temperature coefficient

Is this correct?

• it looks fine; why do you want to replace it? – dandavis Aug 20 '18 at 21:16
• The 4th band is Gold, I've read that means it's an exception. An exception to what? Also, look at your schematic, it should tell you the value of the resistor at R910. If you don't have a schematic then why not whip out the multimeter? You don't want to change resistor values on a circuit... – user103380 Aug 20 '18 at 21:18
• Gold in 4th position is perfectly fine for 5-band code. Now, the silver in 3rd position is totally unexpected. – Maple Aug 20 '18 at 21:20
• I believe it's a .22 Ohm, 5%, 100 ppm/K current sense resistor that someone used silver instead of gray on the 5th band. However, without a diagram or circuit description so that we can know what this resistor was being used for, this is just my best guess. – CoreyF Aug 20 '18 at 21:45
• @CoreyF The idea that this could be 6-band code crossed my mind, because there is something like faint band (violet?) before red. But there is neither gray nor silver code for ppm. And silver in 5th position (if that is 5-band code) is not a problem. Problem with silver in the middle. – Maple Aug 20 '18 at 22:42
