Ohm Bands

6.8 MΩ resistor colour code

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

How much it can take

Current and dissipation across the resistor, and the package you need. The suggested rating keeps a factor of two in hand, which is what anyone building a board actually does.

What ten of them actually cost

The price everyone quotes is the reel price. If you want ten, you cannot buy the reel — and the real figure is usually several times higher per piece.

Per piece, ten costs 9.6× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.

Values that can overlap this one

At ±5% the tolerance bands of neighbouring values run into each other. A part sold as one of these could measure the same as a 6.8 MΩ — which is why measuring beats reading when it matters.
