84, hang on I was only 11 lol.

No problem. It's still a good way to learn.. I learnt how to re-size a photo from my usb microscope.
Gotta love this forum! If only these forums were around in '84' when I failed my part two electronics on maths.

Glad you love it. I spend most of my time on here.

@ 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.

@ Adam, Hehe I was 17 and in my second job as a telephone engineer. Mad on electronics and Hi-Fi. BUT got into cars and girls... nuff said...

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?

 

[davenn]

just makes for easy component placement and physical size

 

[Martaine2005]

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

 

[Martaine2005]

Thanks Davenn, I will shut up and take your word..

 

[davenn]

naaa ... tis always good to ask questions

 

[Martaine2005]

Thanks davenn. A ban crossed my mind for posting too many photos in quick consession..
Blame Adam, he showed me how to do it..!!

 

[davenn]

its all good buddy

hope you are enjoying the forums

 

[Martaine2005]

Luv it.....I'm getting addicted.. You can call me professor in 5 years.

Thanks Dave, never seen one like that before. You learn things everyday.
