SMD code 05A — 1.1 Ω
A surface-mount resistor has no bands. This one is an EIA-96 marking: code 5 is 1.1 in the E96 series, A multiplies by 1. Parts marked this way are usually ±1%.
05A
reads as
1.1 Ω
The same part, in bands
The through-hole version of 1.1 Ω carries 4 colour bands instead.
Everything about 1.1 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
1.1 Ω is printed several ways depending on the part's precision and size. A board can carry all of them at once.
How much it can take
| Across it | Dissipated | Smallest package that copes |
|---|---|---|
| 5 V | 22.7 W | no standard part — needs a power resistor or a heatsink |
| 12 V | 131 W | no standard part — needs a power resistor or a heatsink |

Codes you will mistake it for
One character apart from 05A. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
