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

Band by band
| Band | Colour | Meaning |

| 2 | Brown | 2nd digit — 1 |
| 3 | Brown | Multiplier — ×10 |
| 4 | Gold | Tolerance — ±5% |
How much it can take
Current and dissipation across the resistor, and the package you need. The suggested rating keeps a factor of two in hand, which is what anyone building a board actually does.
| Across it | Current | Dissipated | Package to pick |
|---|---|---|---|
| 3.3 V | 6.47 mA | 21.4 mW | 1/8 W |
| 5 V | 9.8 mA | 49 mW | 1/8 W |
| 12 V | 23.5 mA | 282 mW | 1 W |
| 24 V | 47.1 mA | 1.13 W | 5 W |

Values that can overlap this one
At ±5% the tolerance bands of neighbouring values run into each other. A part sold as one of these could measure the same as a 510 Ω — which is why measuring beats reading when it matters.
