140 Ω resistor colour code
Five bands: Brown · Yellow · Black · Black · 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.

A brown band allows this much drift.

E96
A 1% precision value. Five bands, not four.
Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Brown | 1st digit — 1 |
| 2 | Yellow | 2nd digit — 4 |
| 3 | Black | 3rd digit — 0 |
| 4 | Black | Multiplier — ×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 | 23.6 mA | 77.8 mW | 1/4 W |
| 5 V | 35.7 mA | 179 mW | 1/2 W |
| 12 V | 85.7 mA | 1.03 W | 5 W |
| 24 V | 171 mA | 4.11 W | no standard part — needs a power resistor or a heatsink |

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 11.8× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.
Stocked in ±1%, rated 1/16 W to 1/8 W.
