8.2 Ω resistor colour code
Four bands: Grey · Red · Gold · 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 |
|---|---|---|
| 1 | Grey | 1st digit — 8 |
| 2 | Red | 2nd digit — 2 |
| 3 | Gold | Multiplier — ×0.1 |
| 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 | 402 mA | 1.33 W | 5 W |
| 5 V | 610 mA | 3.05 W | no standard part — needs a power resistor or a heatsink |
| 12 V | 1.46 A | 17.6 W | no standard part — needs a power resistor or a heatsink |
| 24 V | 2.93 A | 70.2 W | no standard part — needs a power resistor or a heatsink |

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 8.8× 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 Ω — which is why measuring beats reading when it matters.
