@mbmb37001 something like this or even like this should work but we have to see what you see. Post a picture of your complete PSU with your questions. That way we can see what you see and hopefully help you out further. Adding images to an existing question

I have seen the ones you posted, but they are 30 mm. Mine is 20 mm


@mbmb37001 well you did not mention the detail about the length ;)These ones should work.

Now, you do need to figure out why the fuses blow. of course, unless you touched something accidentally.


@oldturkey03 Yes , this is the one , but unfortunately they have been out of stock for a long time. Well i dont know why the fuse is blown, but i was thinking to change it and se if it blows again, before i buy another complete power board, they are quite expensive.



Buy the longer fuse.

If the leads of the fuse are long enough they can be bent under the fuse to fit into the thru holes on the board to be soldered there i.e. fuse sits on top of the leads.

As long as they don't touch each other (or anything else), it will be OK. You can even put heatshrink tubing over the leads if you want to to prevent them accidentally touching anything that they shouldn't.

The fuse can even stand a bit higher off the board as well. It doesn't have to lie flat on it.

A fuse is a fuse is a fuse. As long as its rating is the same you can make it fit the circumstances.


@jayeff Thanks, Yes i will try and fit a 30 mm fuse if it is possible.
