    @ Hevans1944
    I checked it as one would do a diode check (continuity) and beeped both ways. Only difference is lead to lead of meter was 0,2 and across the Item was 0.7 both ways. Still, both are OL I think.

    Guys
    They are fuses !! a very common type in modern electronics :)

    Now I haven't looked into the specifics of their coding in the past but it would be reasonable to expect

    N5 = 500mA
    N25 = 25mA

    OMG, that certainly makes sense but? Why the transistor body? Why the flat front? I have some through hole fuses here now. They are round, light brown-ish/red with T 3.15a or what ever.
    Very interesting though and would explain my OL measurements.

    Incidently, if N5 = 500ma
    why not N25 =2500ma ie 2.5 A or is that just plain daft on my account?

    just makes for easy component placement and physical size

    Very intersting... Gonna pop this bugger and see what amperage makes it work.
    Thanks davenn.

    As per the first photo I posted, the board has a lot of room to accomadate a 'traditional' on-board fuse.
    This photo is both a 'traditional' and the component I have for size comparison.

    tis a similar numbering scheme to small value resistors and capacitors
    take the N in front of the number as a decimal point

    As I said earlier, I haven't delved deeply into the info for those particular fuses, tho have replaced many

    It's really just a manufacturer/designers choice .... you could ask you Q of dozens of similar components
