Tolerance
The preferred 4-band example uses ±5% tolerance. Three-band examples have no tolerance stripe and are generally read as ±20%; four-, five-, and six-band examples show tolerance explicitly.

The Gold tolerance band is read at the right-hand end.
Tolerance and temperature coefficient
These specifications describe permitted variation; they do not change the nominal resistance encoded by the significant digits and multiplier.
Temperature coefficient
Only the six-band example adds TCR. Its final Brown band represents ±100 ppm/K, describing permitted resistance change per kelvin relative to the component’s specified reference temperature.

Digit positions use Black–White. A leading black band is accepted as digit 0, although it is uncommon because the leading zero is redundant. Multiplier, tolerance, and TCR positions show only colours valid for that role. No band means ±20% tolerance on a 3-band resistor.
