SMD code 11A — 1.27 Ω
A surface-mount resistor has no bands. This one is an EIA-96 marking: code 11 is 1.27 in the E96 series, A multiplies by 1. Parts marked this way are usually ±1%.

1.27 Ω
The same part, in bands
The through-hole version of 1.27 Ω carries 5 colour bands instead.
Everything about 1.27 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
1.27 Ω 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 11A. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
