SMD code 21A — 1.62 Ω
A surface-mount resistor has no bands. This one is an EIA-96 marking: code 21 is 1.62 in the E96 series, A multiplies by 1. Parts marked this way are usually ±1%.

Codes you will mistake it for
One character apart from 21A. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
