SMD code 921 — 920 Ω
A surface-mount resistor has no bands. This one is a three-digit marking: 92 × 10¹. Parts marked this way are usually ±5% or ±2%.

reads as
920 Ω
Same value, other markings
920 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 921. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
