I need to replace a resistor and can't seem to figure out the value. The body color is gray and the bands are green, blue, gold, gold, white. I googled for precision resistor color codes, but had no luck. Any ideas?
I am only 95% sure about this, and I trust if I am wrong there will be plenty of other responses to your post..
Green, Blue, Gold = 0.056 Ohms, next Gold = 2% tolerance, White = 100 ppm tempco
The
ideas?
If you measure it with your DMM, which you _should_ have, it should measure 5.6 ohms, plus or minus 5%. However most DMMs have a half ohm or so of resistance in the test leads, etc.
I'm assuming that if you can read the colors, then it hasn't been overheated, and it should still be its original value.
You'e 95% wrong. Here, duncecap, go sit in the corner and play with this.
And you've got detention for the rest of the semester!
OK, so I couldn't remember the multiplier off the top of my head, and I stated that I wasn't sure -- and that others like yourself would correct me if I was wrong -- which you did. I've been working with 1% hi-rel Mil resistors for so long, I can't remember everything.
How about that white band on the end, though??? It is either a tempco band, or a failure-rate band -- that much I know.
It's probably an NFR25H (non-flammable/fusible-metalfilm-resistor) where the white band indicates a power of 0.5W.
The band for temp.coeff. is used only with precision-resistors (which always have more than 5 bands on it)
