19.1 Ω resistor colour code
Five bands: Brown · White · Brown · 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.

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 | White | 2nd digit — 9 |
| 3 | Brown | 3rd digit — 1 |
| 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 | 173 mA | 570 mW | 2 W |
| 5 V | 262 mA | 1.31 W | 5 W |
| 12 V | 628 mA | 7.54 W | no standard part — needs a power resistor or a heatsink |
| 24 V | 1.26 A | 30.2 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 7.6× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.

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 19.1 Ω — which is why measuring beats reading when it matters.
If you do not have one
Standard values that land within 1% of 19.1 Ω when combined.
