SMD code 68H — 49.9 Ω
A surface-mount resistor has no bands. This one is an EIA-96 marking: code 68 is 4.99 in the E96 series, H multiplies by 10. Parts marked this way are usually ±1%.

49.9 Ω
The same part, in bands
The through-hole version of 49.9 Ω carries 5 colour bands instead.
Everything about 49.9 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
49.9 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 68H. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
