SMD code 91C — 866 Ω
A surface-mount resistor has no bands. This one is an EIA-96 marking: code 91 is 8.66 in the E96 series, C multiplies by 100. Parts marked this way are usually ±1%.

Codes you will mistake it for
One character apart from 91C. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
