8.2 MΩ resistor colour code
Four bands: Grey · Red · Green · 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 | 0.402 µA | 1.33 µW | 1/8 W |
| 5 V | 0.61 µA | 3.05 µW | 1/8 W |
| 12 V | 1.46 µA | 17.6 µW | 1/8 W |
| 24 V | 2.93 µA | 70.2 µW | 1/8 W |
What you can actually get
Standard on paper, absent from the shelf.
8.2 MΩ is a proper E12 value, but no part carrying it is currently held for assembly. The nearest value you will actually find is 8.2 MΩ.
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 10.3× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.

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 8.2 MΩ — which is why measuring beats reading when it matters.
