Since Edward V. Sundt founded Littelfuse in 1927, we’ve been driven by innovation. Sundt invented the first small, fast-acting protective fuse to prevent sensitive reference standard from burning out. From that pioneering first step, Littelfuse has gone on to define the standards of the circuit protection industry.
And we continue to set new benchmarks. As the world leader in circuit protection, Littelfuse possesses nine core technologies, as well as some of the industry’s most respected brands – Teccor®, Wickmann and Pudenz.
Littelfuse products are vital components in allmost every market that uses electrical energy, from consumer electronics to automobiles, commercial vehicles and industrial equipment.
