Sourcing a certain component

[Jtroutt19]

Hey guys Not sure where to put this but I am trying to find a fuse.

It is SMD fuse that is on a
Toshiba SSD 128GB
THNSNS128GMCP

Anyone know where I can get this fuse or find out some info about the specs on it?

Do you have good clear pictures of what we are dealing with?

Nope not at the moment. A friend brought it to me and I did some microscope inspection and then some continuity testing of the fuse and diode Fuse it blown. Didn't think to take a picture of it. It Almost looks like one of the fuses on a nintendo 3DS XL board. Got the letter "P" on it as well.

The bad part is that the letter marking on the fuse is not standard, if you look at the spec sheet of BOURNS (P= 1.5A) and Lilltle fuse (P= 3.0A).
So the pictures and where it is used may help.

Ok here are a couple pictures. There is an arrow on the one pointed at the fuse.

Any thoughts?

Figure 5 to 6 watts peak while writing so that's around 1.5 to 1.75 amps. A 1.5 amp fuse should be close. You could also try starting small .25A and working your way up until they stop blowing. A really brave man might just put an amp meter in place of the fuse and see what the current draw really is. Probably only a good idea after you figure out why the fuse blew.

Or check the resistance on the load side of the fuse to see if it shows very low resistance or not, that will be a start.
It may have crowbar protection diode after the fuse or shorted MLCC.

The part looks too tall in height to be a smt fuse? All the smt fuses I've seen are pretty flat and not gray color. I wonder if it is a ferrite chip bead inductor? I guess a fuse is better to limit the smoke if something shorts.
