150 Ω resistor colour code
Four bands: Brown · Green · Brown · 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 |

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 | 22 mA | 72.6 mW | 1/4 W |
| 5 V | 33.3 mA | 167 mW | 1/2 W |
| 12 V | 80 mA | 960 mW | 2 W |
| 24 V | 160 mA | 3.84 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 9.1× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.

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 150 Ω — which is why measuring beats reading when it matters.
- 143 Ω141.57 Ω–144.43 Ω
- 147 Ω145.53 Ω–148.47 Ω
- 154 Ω152.46 Ω–155.54 Ω
- 158 Ω156.42 Ω–159.58 Ω
- 160 Ω152 Ω–168 Ω
