Four Bands

6.8 kΩ resistor colour code

Four bands: Blue · Grey · Red · Gold. The first two give the digits, the third multiplies, the fourth states how far off the real part may be.

6,800 ohms

Real range at ±5%

6.46 kΩ – 7.14 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 6.8 kΩ looks different.
