102 kΩ resistor colour code
Five bands: Brown · Black · Red · Orange · 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
102 kΩ
102,000 ohms
Real range at ±1%
100.98 kΩ – 103.02 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 | Red | 3rd digit — 2 |
| 4 | Orange | Multiplier — ×1k |
| 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 | 32.4 µA | 107 µW | 1/8 W |
| 5 V | 49 µA | 245 µW | 1/8 W |
| 12 V | 118 µA | 1.41 mW | 1/8 W |
| 24 V | 235 µA | 5.65 mW | 1/8 W |

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 102 kΩ — which is why measuring beats reading when it matters.
If you do not have one
Standard values that land within 1% of 102 kΩ when combined.
