Short question here: could someone help me identify this component?
Probably a fuse, because of the "F3" marking next to it, and because I have seen this cryptic marking before on a Littlefuse fuse.
A photo with more "context", and a look at the traces of the PCB, would help to make sure it is indeed a fuse.
If Littlefuse's markings happen to be universal, of which I am not sure, you can find the specifications for an SMD fuse marked "A" (and others) in this data sheet.
You can find them here: it’s indeed a fuse.. (0805 6V 0.35A, 250mA and resettable)
