MINI® Blade Fuses Rated 32V
The MINI® Fuse is the standard for vehicle circuit protection. Its miniature design meets the
need for more circuits to be protected while utilizing less space, and its ability to cope with
high temperatures in adverse environments makes the MINI® Fuse of recommended choice
for protection.

Blade Fuses
*Component Level Temperature = the maximum ambient temperature that a
single fuse will survive. This does not factor-in the heat from a populated
fuse box, but does include the heat from the current load with the proper
rerating. **System Level Temperature represents the ambient temperature of
the fuse box at a location within the vehicle. The temperature within a
populated fuse box (in a given location) will be higher. The limiting factor is
the plating. Sn-plating’s temperature limit is ≈130°C, and Ag-plating allows up
to 150°C at the terminal interface.
