SMD code 213 — 21 kΩ
A surface-mount resistor has no bands. This one is a three-digit marking: 21 × 10³. Parts marked this way are usually ±5% or ±2%.
213
reads as
21 kΩ
The same part, in bands
The through-hole version of 21 kΩ carries 5 colour bands instead.
Everything about 21 kΩ — power ratings, what ten cost, what is in stock.
Same value, other markings
21 kΩ 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 213. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
