Hi all,
sorry for the dumb question, but I'm not finding any good info on the net
it seems. I often see in old (CRT) TV chassis some resistors with
a standard 4 bands code (the 4th is Gold) plus a 5th
band always yellow, for example Brown Black Black Gold Yellow (measures 10
ohms as expected).
What's the meaning of the additional yellow band?
Thanks in advance
Frank

In which case why on earth would you have both? ("Lieu" implies

R1 = brown, black, gold, gold.
R2 = brown, black, back, silver, brown.
Can you say what their values and tolerances are ?

R1 = brown, black, gold, gold.
R2 = brown, black, back, silver, brown.

the resistors I'm talking about have both gold (as 4th band) and yellow

as 5th band.

1 ohm, 1%
Well, I guess the answer to my original question was probably a
temperature tolerance band or something similar.
Seems I am not alone.

Yes, obviously the presence of gold means it's not substituting for gold. This explains:

The 3 first are the value (the last one is the multiplier).
Then, there is the tolerance.
And finally it can exist a 5th one, the thermal drift.
