SMD code 4300 — 430 Ω
A surface-mount resistor has no bands. This one is a four-digit marking: 430 × 10⁰. Parts marked this way are usually ±1% or tighter.

reads as
430 Ω
The same part, in bands
The through-hole version of 430 Ω carries 4 colour bands instead.
Everything about 430 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
430 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 4300. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
