620 Ω resistor colour code
Four bands: Blue · Red · Brown · 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 |

| 2 | Red | 2nd digit — 2 |
| 3 | Brown | Multiplier — ×10 |
| 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 | 5.32 mA | 17.6 mW | 1/8 W |
| 5 V | 8.06 mA | 40.3 mW | 1/8 W |
| 12 V | 19.4 mA | 232 mW | 1/2 W |
| 24 V | 38.7 mA | 929 mW | 2 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 9.6× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.
Stocked in ±1% and ±5%, rated 1/16 W to 1/8 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 620 Ω — which is why measuring beats reading when it matters.
