SMD code 1203 — 120 kΩ
A surface-mount resistor has no bands. This one is a four-digit marking: 120 × 10³. Parts marked this way are usually ±1% or tighter.

120 kΩ
The same part, in bands
The through-hole version of 120 kΩ carries 4 colour bands instead.
Everything about 120 kΩ — power ratings, what ten cost, what is in stock.
Same value, other markings
120 kΩ 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 1203. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
