54.9 kΩ resistor colour code
Five bands: Green · Yellow · White · Red · 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.
Nominal
54.9 kΩ
54,900 ohms
Real range at ±1%
54.351 kΩ – 55.449 kΩ
A brown band allows this much drift.
Series
E96
A 1% precision value. Five bands, not four.
Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Green | 1st digit — 5 |
| 2 | Yellow | 2nd digit — 4 |
| 3 | White | 3rd digit — 9 |
| 4 | Red | Multiplier — ×100 |
| 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 | 60.1 µA | 198 µW | 1/8 W |
| 5 V | 91.1 µA | 455 µW | 1/8 W |
| 12 V | 219 µA | 2.62 mW | 1/8 W |
| 24 V | 437 µA | 10.5 mW | 1/8 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 7.3× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.
Stocked in ±0.1% and ±0.5% and ±1%, rated 1/20 W to 1/4 W.

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 54.9 kΩ — which is why measuring beats reading when it matters.
If you do not have one
Standard values that land within 1% of 54.9 kΩ when combined.
