100mA 500VDC slow ceramic fuse
 
I'm looking for 100mA 500VDC slow ceramic fuse, help will be appreciated.

And the physical dimentions are:

6X32mm

Google 3AG fuse. Digikey, Mauser, Parts Express, Conrad....they all carry those. E

Farnell 15A-30A 500VDC rated
Parts Express minimum 500mA not sure 500VDC
Mouser 8A-60A 500VDC rated
Conrad not sure 500VDC

A fast 500mA will be safer than no fuse.

A slow 200mA to 300mA is possibly around the same rupture time as a fast 500mA.

I'm looking for 100mA 500VDC slow or fast.:confused:

I thought you said slow 100mA.
I'm pointing out that a fast with roughly double the rating will rupture in about the same time.

If a slow 100mA is what you need, then you may get similar protection from a fast 200mA.

That is not all that far from fast 500mA.

Can you see where my suggestions and comments are going?

Any fast 500mA fuse is safer than no fuse.
If you can't get a 500Vdc rated fuse as low as T100mA then maybe an F500mA would be the next best.

Littelfuse 325.125, 326.125 are rated at 0.125A, 250VAC. Closest I came to. The voltage rating should not be that important, a regulatory thing (CE, CSA, UL), more like guidelines, as Captain Barbossa said.... E

The voltage rating is very important.

If the wire ruptures but the arc continues to pass across the gap, then the rupturing of the fuse wire has not isolated the supply from the load.
