SMD code 03A — 1.05 Ω
A surface-mount resistor has no bands. This one is an EIA-96 marking: code 3 is 1.05 in the E96 series, A multiplies by 1. Parts marked this way are usually ±1%.

1.05 Ω
The same part, in bands
The through-hole version of 1.05 Ω carries 5 colour bands instead.
Everything about 1.05 Ω — power ratings, what ten cost, what is in stock.

Codes you will mistake it for
One character apart from 03A. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
