Blade Fuses
MICRO2™ Blade Fuses Rated 32V
The MICRO2™ Fuse is the new standard for vehicle circuit protection. Its sub-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 MICRO2™ Fuse of
recommended choice for protection.
Black amperage stamps are used on the 20A & 25A / light colored housings to improve
contrast for vision system inspection.

Time-Current 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.
