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

33 ohms
Real range at ±5%
31.35 Ω – 34.65 Ω
A gold band allows this much drift.

Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Orange | 1st digit — 3 |
| 2 | Orange | 2nd digit — 3 |
| 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 33 Ω looks different.
