Our humble roots date back to 1927, where, in the back of a garage on Chicago's northside, our founder, Edward Sundt, developed a small, fast-acting, protective fuse for use in sensitive test meters.

Sundt wanted to call his new company producing these small fuses, "Little Fuse," but wasn't allowed to trademark two such common words. So, instead he went with the one-word, misspelled "Littelfuse." For more than 95 years, Littelfuse has pioneered innovative products that help empower a sustainable, connected, and safer world.

With the ever-evolving electrification and electronification of customer applications, our product technologies are closely linked to sustainable applications such as electric vehicles and EV charging infrastructure, renewable energy and energy storage, factory automation, power management and more.
