13.3 Ω resistor colour code
Five bands: Brown · Orange · Orange · Gold · Brown. The first three give the digits — a precision value needs all three — then the multiplier, then how far off the real part may be.

Real range at ±1%
13.167 Ω – 13.433 Ω
A brown band allows this much drift.
Series
E96
A 1% precision value. Five bands, not four.
Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Brown | 1st digit — 1 |
| 2 | Orange | 2nd digit — 3 |
| 3 | Orange | 3rd digit — 3 |
| 4 | Gold | Multiplier — ×0.1 |
| 5 | Brown | Tolerance — ±1% |
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 | 248 mA | 819 mW | 2 W |
| 5 V | 376 mA | 1.88 W | 5 W |
| 12 V | 902 mA | 10.8 W | no standard part — needs a power resistor or a heatsink |
| 24 V | 1.8 A | 43.3 W | no standard part — needs a power resistor or a heatsink |

The same value, marked differently
Values that can overlap this one
At ±1% the tolerance bands of neighbouring values run into each other. A part sold as one of these could measure the same as a 13.3 Ω — which is why measuring beats reading when it matters.
If you do not have one
Standard values that land within 1% of 13.3 Ω when combined.
