Resistor color not correct
« on: September 27, 2021, 03:31:20 pm »
Hi, when i started this hobby i ordered 100 piece 820 ohm resistors.
They dont have a brown line, instead they have a black line ( 82 ohm )
Have you ever had wrong labeling before ?

bye

Or you got the wrong product and the label is correct.

No i mean the paint color on the resistor itself.
The bag says the right 820 ohm, the paint is black not brown.

Manufacturer order code? How many rings? Picture of the suspect? What is the actually measured resistance?

Ah, and try to move this question to the Beginner section, please.

I'll second the 'have you actually measured them' question, and my second question would be where were they ordered from - a mainstream supplier, or somewhere like ebay or Amazon, which I'd consider to be considerably sketchier as component sources?

If it jams, force it.  If it breaks, you needed a new one anyway...

Most leaded resistors today have three-ring colour codes for the digits, regardless of whether they're E12, E24; E48 or E96  series.

An 820-ohm resistor would then be gray-red-black-black plus the tolerance ring.

Please never do that again.  We don't need a 1 minute out of focus, badly exposed and glare filled video.  Post a *photo* with decent resolution.

Anyway, yeah that looks wrong.  I would expect to see either grey/red/brown + gold or grey/red/black/black + gold.  It looks to me like someone decided that if the multiplier is 10^0 they could just leave the band off.

Where did you get these?

In a german shop a very long time ago, the bag says : made in taiwan roc.
