Mini Auto Blade Fuse 2A 3A 4A 5A 7.5A 10A 15A 20A 25A
Overview
The MINI® Fuse is quickly becoming the new standard for vehicle
circuit protection throughout the world. Its miniature design,
patented by Littelfuse, 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 the
recommended choice for protection.
Features
Breakthrough current, labeled on the fuse as IR, is the maximum
current that a fuse can safely stop in the event of a short
circuit.
Fast-acting fuses open circuits quickly when surges are detected.
Fuses with blown fuse indicator have a light that turns on when the
fuse blows.

Datasheet
Operating Principle
Nonindicating automotive blade fuses open within seconds of being
exposed to overloads and short circuits. They have no indicator for
identifying a blown fuse, so they're sometimes used with an
indicating fuse block or cover.
Automotive blade fuses are the most commonly used type of
automotive fuse for protecting electrical systems and components
against overcurrent. These 32VDC plug-in style fuses have a plastic
housing with two blade-style contacts that fit into compatible fuse
block or holder. Their housing is usually color-coded by amperage
rating to help prevent installation of a mismatched fuse. The
housing is also transparent for checking whether the fuse element
is intact or has melted.
