620 Ω resistor colour code
Four bands: Blue · Red · Brown · Gold. The first two give the digits, the third multiplies, the fourth states how far off the real part may be.

Real range at ±5%
589 Ω – 651 Ω
A gold band allows this much drift.

E24 only — stocked less often.
Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Blue | 1st digit — 6 |
| 2 | Red | 2nd digit — 2 |
| 3 | Brown | Multiplier — ×10 |
| 4 | Gold | Tolerance — ±5% |
The same value on a five-band part
Precision resistors carry three significant digits instead of two, so the same 620 Ω looks different.
