SMD code 281 — 280 Ω
A surface-mount resistor has no bands. This one is a three-digit marking: 28 × 10¹. Parts marked this way are usually ±5% or ±2%.
281
reads as
280 Ω
The same part, in bands
The through-hole version of 280 Ω carries 5 colour bands instead.
Everything about 280 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
280 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 281. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
