SMD code 1271 — 1.27 kΩ
A surface-mount resistor has no bands. This one is a four-digit marking: 127 × 10¹. Parts marked this way are usually ±1% or tighter.

Same value, other markings
1.27 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 1271. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
