Requesting help identifying the resistor shown in the attached pic. The color bands, which do not seem standard are:
Red
Black
Silver
Gold
Blue
Thank you.
We do have a resistor calculator on our site, which you can access here: https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-resistor-color-code. Based on that color code, it would be 20.8 Ohm with a 0.25% tolerance. I can’t determine the wattage for that part from the photo, and could you please confirm if the first band is indeed red and not brown?

Red, black, gray, gold, blue would be 20.8 ohms +/-0.25%.
However based on the look of the PCB I very much doubt that is the part. It appears to be a current limiting resistor based on position and condition (exploded) so almost certainly a flameproof resistor and not +/-0.25%. IME. that high of a precision resistor is pretty much only used in very precise and expensive measuring circuits which would not have such a crude PCB design.
I would guess that it’s actually brown, black, silver, gold, blue. Which would make it a 0.1 ohm 5% resistor with the blue band being a manufacturer specific band. To me that is a much more likely value in a current limiting application.

My error was to use the 5-band calculator when it is a 4-band resistor. The blue band on the end is manufacturer specific.
Outstanding! Thank you.
