SMD code 225 — 2.2 MΩ
A surface-mount resistor has no bands. This one is a three-digit marking: 22 × 10⁵. Parts marked this way are usually ±5% or ±2%.
225
reads as
2.2 MΩ
The same part, in bands
The through-hole version of 2.2 MΩ carries 4 colour bands instead.
Everything about 2.2 MΩ — power ratings, what ten cost, what is in stock.
Same value, other markings
2.2 MΩ 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 225. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
