Standard color bands used on through-hole resistors.
Color → digit / multiplier / tolerance
| Color | Digit | Multiplier | Tolerance |
|---|---|---|---|
| Black | 0 | × 1 | — |
| Brown | 1 | × 10 | ±1% |
| Red | 2 | × 100 | ±2% |
| Orange | 3 | × 1K | — |
| Yellow | 4 | × 10K | — |
| Green | 5 | × 100K | ±0.5% |
| Blue | 6 | × 1M | ±0.25% |
| Violet | 7 | × 10M | ±0.1% |
| Gray | 8 | — | ±0.05% |
| White | 9 | — | — |
| Gold | — | × 0.1 | ±5% |
| Silver | — | × 0.01 | ±10% |
Examples (4-band)
| Bands | Value | Tolerance |
|---|---|---|
| Brown Black Red Gold | 1.0 kΩ | ±5% |
| Red Red Red Gold | 2.2 kΩ | ±5% |
| Yellow Violet Orange Gold | 47 kΩ | ±5% |
| Brown Black Green Gold | 1.0 MΩ | ±5% |
| Brown Black Black Gold | 10 Ω | ±5% |
Notes
- 5-band adds a third significant digit before the multiplier.
- 6-band uses the extra band for temperature coefficient (ppm/°C).
Frequently asked questions
Which end is first?
The band closest to the lead is first. Gold/silver is almost always tolerance (rightmost).
