Ohm Bands

6.81 Ω resistor colour code

Five bands: Blue · Grey · Brown · Silver · Brown. The first three give the digits — a precision value needs all three — then the multiplier, then 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 6.4× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.

The same value, marked differently

Surface mount

6R8· three-digit, nearest only

6R81· four-digit, precision parts

81A· EIA-96, for the smallest parts

Three digits carry two significant figures, so they cannot write 6.81 Ω — 6R8 means 6.8 Ω. A part at this value is marked 6R81.

6.8 Ω is the nearest four-band value — -0.1% off.

Values that can overlap this one

At ±1% the tolerance bands of neighbouring values run into each other. A part sold as one of these could measure the same as a 6.81 Ω — which is why measuring beats reading when it matters.
