2.2 MΩ resistor colour code
Four bands: Red · 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 |
|---|---|---|

| 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 | 1.5 µA | 4.95 µW | 1/8 W |
| 5 V | 2.27 µA | 11.4 µW | 1/8 W |
| 12 V | 5.45 µA | 65.5 µW | 1/8 W |
| 24 V | 10.9 µA | 262 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 10.2× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.
Stocked in ±0.1% and ±1% and ±5%, rated 1/20 W to 1/4 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 2.2 MΩ — which is why measuring beats reading when it matters.
