SMD code 47R5 — 47.5 Ω
A surface-mount resistor has no bands. This one is a four-digit marking: the R is the decimal point — 47.5 Ω. Parts marked this way are usually ±1% or tighter.

reads as
47.5 Ω
The same part, in bands
The through-hole version of 47.5 Ω carries 5 colour bands instead.
Everything about 47.5 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
47.5 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 47R5. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
