1.3 Ω resistor colour code
Four bands: Brown · Orange · 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 | Brown | 1st digit — 1 |
| 2 | Orange | 2nd digit — 3 |
| 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 | 2.54 A | 8.38 W | no standard part — needs a power resistor or a heatsink |
| 5 V | 3.85 A | 19.2 W | no standard part — needs a power resistor or a heatsink |
| 12 V | 9.23 A | 111 W | no standard part — needs a power resistor or a heatsink |
| 24 V | 18.5 A | 443 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 1.3 Ω — which is why measuring beats reading when it matters.
