SMD code 530 — 53 Ω
A surface-mount resistor has no bands. This one is a three-digit marking: 53 × 10⁰. Parts marked this way are usually ±5% or ±2%.

53 Ω
Same value, other markings
53 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 | 472 mW | 1 W |
| 12 V | 2.72 W | no standard part — needs a power resistor or a heatsink |

Codes you will mistake it for
One character apart from 530. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
