SMD code 34C — 221 Ω
A surface-mount resistor has no bands. This one is an EIA-96 marking: code 34 is 2.21 in the E96 series, C multiplies by 100. Parts marked this way are usually ±1%.

Same value, other markings
221 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 34C. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
