30 Ω resistor colour code
Four bands: Orange · Black · Black · Gold. The first two give the digits, the third multiplies, the fourth states how far off the real part may be.
Nominal

Real range at ±5%
28.5 Ω – 31.5 Ω
A gold band allows this much drift.

E24 only — stocked less often.
Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Orange | 1st digit — 3 |
| 2 | Black | 2nd digit — 0 |
| 3 | Black | Multiplier — ×1 |
| 4 | Gold | Tolerance — ±5% |
The same value on a five-band part
Precision resistors carry three significant digits instead of two, so the same 30 Ω looks different.
