Low Profile MINI® Blade Fuses Rated 58V
The Low Profile MINI® fuse has similar performance characteristics as the standard MINI®
fuse. The lower overall height allows for more space and weight savings. The Low Profile
MINI® fuse is designed to mate with tuning-fork terminals, which provides additional weight
and material savings in fuse box designs by eliminating the need for female box terminals.

Temperature Rerating Curve

*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.
† Only offered for the 10.0mm series.
