1.05 kΩ resistor colour code
Five bands: Brown · Black · Green · Brown · 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
1.05 kΩ
1,050 ohms
Real range at ±1%
1.0395 kΩ – 1.0605 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 | Brown | 1st digit — 1 |
| 2 | Black | 2nd digit — 0 |
| 3 | Green | 3rd digit — 5 |
| 4 | Brown | Multiplier — ×10 |
| 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 | 3.14 mA | 10.4 mW | 1/8 W |
| 5 V | 4.76 mA | 23.8 mW | 1/8 W |
| 12 V | 11.4 mA | 137 mW | 1/2 W |
| 24 V | 22.9 mA | 549 mW | 2 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 9.5× 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 1.05 kΩ — which is why measuring beats reading when it matters.
If you do not have one
Standard values that land within 1% of 1.05 kΩ when combined.
