SMD code 70R0 — 70 Ω
A surface-mount resistor has no bands. This one is a four-digit marking: the R is the decimal point — 70.0 Ω. Parts marked this way are usually ±1% or tighter.
70R0
reads as
70 Ω
Same value, other markings
70 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 70R0. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
