180 kΩ resistor colour code
Four bands: Brown · Grey · Yellow · Gold. The first two give the digits, the third multiplies, the fourth states how far off the real part may be.
Nominal
180 kΩ
180,000 ohms
Real range at ±5%
171 kΩ – 189 kΩ
A gold band allows this much drift.

Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Brown | 1st digit — 1 |
| 2 | Grey | 2nd digit — 8 |
| 3 | Yellow | Multiplier — ×10 k |
| 4 | Gold | Tolerance — ±5% |
The same value on a five-band part
Precision resistors carry three significant digits instead of two, so the same 180 kΩ looks different.
