SMD code 5105 — 51 MΩ
A surface-mount resistor has no bands. This one is a four-digit marking: 510 × 10⁵. Parts marked this way are usually ±1% or tighter.

Codes you will mistake it for
One character apart from 5105. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
