11 Ω resistor colour code
Four bands: Brown · Brown · Black · 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 | Brown | 1st digit — 1 |
| 2 | Brown | 2nd digit — 1 |
| 3 | Black | Multiplier — ×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 | 300 mA | 990 mW | 2 W |
| 5 V | 455 mA | 2.27 W | 5 W |
| 12 V | 1.09 A | 13.1 W | no standard part — needs a power resistor or a heatsink |
| 24 V | 2.18 A | 52.4 W | no standard part — needs a power resistor or a heatsink |

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

- 10.5 Ω10.395 Ω–10.605 Ω
- 10.7 Ω10.593 Ω–10.807 Ω
