SMD code 6R8 — 6.8 Ω
A surface-mount resistor has no bands. This one is a three-digit marking: the R is the decimal point — 6.8 Ω. Parts marked this way are usually ±5% or ±2%.
6R8
reads as
6.8 Ω
The same part, in bands
The through-hole version of 6.8 Ω carries 4 colour bands instead.
Everything about 6.8 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
6.8 Ω is printed several ways depending on the part's precision and size. A board can carry all of them at once.

Codes you will mistake it for
One character apart from 6R8. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
