SMD code 40H — 25.5 Ω
A surface-mount resistor has no bands. This one is an EIA-96 marking: code 40 is 2.55 in the E96 series, H multiplies by 10. Parts marked this way are usually ±1%.

25.5 Ω
The same part, in bands
The through-hole version of 25.5 Ω carries 5 colour bands instead.
Everything about 25.5 Ω — power ratings, what ten cost, what is in stock.
Same value, other markings
25.5 Ω is printed several ways depending on the part's precision and size. A board can carry all of them at once.
How much it can take
| Across it | Dissipated | Smallest package that copes |

Codes you will mistake it for
One character apart from 40H. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
