SMD code 6650 — 665 Ω
A surface-mount resistor has no bands. This one is a four-digit marking: 665 × 10⁰. Parts marked this way are usually ±1% or tighter.

665 Ω
The same part, in bands
The through-hole version of 665 Ω carries 5 colour bands instead.
Everything about 665 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
665 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 6650. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
