Alright, this one seems like a gimme, but look closer (yes, at my super crappy picture). These do not seem to obey normal band nomenclature.
The top resistor colors from L-R
Red - Black - Brown - Gold - Orange.
Normal 5-band decoding would say this is a 20.1Ω resistor with tolerance orange. Nope, this came marked as a 200Ω, and measures out accordingly. Second, orange is not a tolerance marking according to my charts or those I found during a web search. So this one seems like perhaps the first three colors give the resistance (as in a 4 band), the gold is tolerance (5%) and orange is temperature coefficient.
The bottom resistor reads (L-R)
Brown - Grey - Black - Gold - Orange
This can be particularly confusing as if you use standard decoding, you come up with 18Ω (which measures correctly) and again, orange tolerance. However, if you use the scheme from the first resistor, you also get 18Ω but with an orange temperature rating.
This is the first I've run into this discrepancy. Is this a carbon comp thing?
