SMD code 7R15 — 7.15 Ω
A surface-mount resistor has no bands. This one is a four-digit marking: the R is the decimal point — 7.15 Ω. Parts marked this way are usually ±1% or tighter.
7R15
reads as
7.15 Ω
The same part, in bands
The through-hole version of 7.15 Ω carries 5 colour bands instead.
Everything about 7.15 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
7.15 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 7R15. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
