SMD code 40E — 25.5 kΩ

A surface-mount resistor has no bands. This one is an EIA-96 marking: code 40 is 2.55 in the E96 series, E multiplies by 10000. Parts marked this way are usually ±1%.

Everything about 25.5 kΩ — power ratings, what ten cost, what is in stock.

Same value, other markings

25.5 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 40E. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
