680 kΩ resistor colour code
Four bands: Blue · Grey · Yellow · 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 |
|---|---|---|

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 | 4.85 µA | 16 µW | 1/8 W |
| 5 V | 7.35 µA | 36.8 µW | 1/8 W |
| 12 V | 17.6 µA | 212 µW | 1/8 W |
| 24 V | 35.3 µA | 847 µW | 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 11.8× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.
Stocked in ±1% and ±5%, rated 1/20 W to 1/2 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 680 kΩ — which is why measuring beats reading when it matters.
