A popular adage regarding a printed circuit board (PCB) layout is "space is money"...

In the case of fuses, there are a lot of different sizes to to choose from each offering different characteristics and specifications.

A big problem for engineers when specifying the really small fuses is that they are, in general, types of fuses that need to be direct soldered into (or onto) the PCB.  This means that the fuse cannot be readily replaced if there is a problem later on. 

Now where there is a problem...there is a solution...

The microfuse is the answer.  The microfuse is a radial leaded fuse (only a 0.2" spacing lead to lead) that can be either directly soldered into the the PC or can be mounted in a special fuseholder that allows the user to replace the fuse in the field.  The microfuse was first developed in Europe but has spread quickly to the rest of the world and is considered the fastest growing segment of the electronic PCB fuses.
