Characteristic Curves
*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.
