47 Ω resistor colour code
Four bands: Yellow · Violet · Black · 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 | Yellow | 1st digit — 4 |
| 2 | Violet | 2nd digit — 7 |
| 3 | Black | Multiplier — ×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 | 70.2 mA | 232 mW | 1/2 W |
| 5 V | 106 mA | 532 mW | 2 W |
| 12 V | 255 mA | 3.06 W | no standard part — needs a power resistor or a heatsink |
| 24 V | 511 mA | 12.3 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.

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 47 Ω — which is why measuring beats reading when it matters.
