6 resistor bands?

[Halogrunt1234]

I have heard about 5 band resistors, but I didnt even know 6 band resistors existed until I found it in a container full of class-desoldered components.

The band colors are:
White Black White Brown Brown Red
please note that I could have read the colors in reverse order.

Also, I was confused about how it has no silver or gold band to tell tolerance.
The package looks just as any other 1/4 watt blue resistor would be shaped as, but I am confused about the six bands.

I would just like to know how to read it, and what it might be used for.

Thanks

band 1-number
band 2-number
band 3-number
band 4-multiplyer
band 5-tolerance
band 6-temperature

Thank you very much
I'm very familiar with the color code and I can figure everything else out.
Thank you

Similar thing I might as well mention, I bought a pack of resistors, assorted, and there are ones in there with just 2 colour bands, and 2 gold stripes. I know there are a few red red gold gold ones. Any idea, or is this just a printing error, some of the others look like they were made in the 60s :lol:

this is not an error(i think) cause red red gol gol = 2,2Ohms in5% tolerance

but to make shure check them with a multy- or Ohmmeter

military resistors often have more bands

Resistor with 4 color bands, the third band is always the multiplier.
If the band is gold the multiplier is 0.1
If the band is silver the multiplier is 0.01
The 4 band is the tolerance
Red, Red, Gold, Gold would be 2.2 ohms 5%.

Aah, so they are incredibly small value ones, whereby the multiplier is actually dividing the value. Thanks a lot!

Actually most Mil spec resistors have a number on them, like 1004 and are typically .01-.1 in tolerance.
