SMD code R287 — 0.287 Ω
A surface-mount resistor has no bands. This one is a four-digit marking: the R leads, so the value is below 1 Ω — 0.287 Ω. Parts marked this way are usually ±1% or tighter.

reads as
0.287 Ω
Same value, other markings
0.287 Ω is printed several ways depending on the part's precision and size. A board can carry all of them at once.
