Four Bands

51 kΩ resistor colour code

Four bands: Green · Brown · Orange · 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%

48.45 kΩ – 53.55 kΩ

A gold band allows this much drift.

The same value on a five-band part

Precision resistors carry three significant digits instead of two, so the same 51 kΩ looks different.
