39 kΩ resistor colour code
Four bands: Orange · White · Orange · 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 |
|---|---|---|

| 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 | 84.6 µA | 279 µW | 1/8 W |
| 5 V | 128 µA | 641 µW | 1/8 W |
| 12 V | 308 µA | 3.69 mW | 1/8 W |
| 24 V | 615 µA | 14.8 mW | 1/8 W |

What ten of them actually cost
The price everyone quotes is the reel price. If you want ten, you cannot buy the reel — and the real figure is usually several times higher per piece.

Per piece, ten costs 7.6× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.
Stocked in ±0.5% and ±1% and ±5%, rated 1/16 W to 0.6 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 39 kΩ — which is why measuring beats reading when it matters.
