SMD code 3906 — 390 MΩ
A surface-mount resistor has no bands. This one is a four-digit marking: 390 × 10⁶. Parts marked this way are usually ±1% or tighter.

reads as
390 MΩ
Same value, other markings
390 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 3906. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
