Hi everyone.

A few days ago I found a 5 bands resistor with gold on the 4th band. According to Wikipedia, that's an older or specialized resistor. The 5th band is the temperature coefficient. I was able to interpret the value of the resistor.

Now I found a 5 band resistor with the following bands: brown (1), black (0), gold (-1), gold (-1), white (9). It can't be a normal resistor because:
· the 3rd band is gold, so there's no way to compose a value with -1;
· the 5th band is white, and there's no tolerance value associated with white.
But there's also no temperature coefficient value associated with white, so it doesn't fit the "older or specialized resistor" layout. White can only be a value or a multiplier.

So, the multiplier and the tolerance switched places, or there's no tolerance band present, or is this something completely different?
