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 test meters from burning out. From that pioneering first step, our company has gone on to define the standards of the circuit protection industry.

In the 1960s, we developed sub-miniature fuses for NASA, which were mission-critical components of the American space program. And in 1976, we introduced the groundbreaking Autofuse® Fast-Acting Fuse for General Motors. Within eight years, it was being designed into vehicles all over the world.

We again revolutionized automotive fuse protection in 1986 with the debut of the space-saving MINI®. Its smaller design allowed for the additional protection of on-board electronic accessories. Recently, we introduced the world`s smallest high surge current protection thyristor, the Teccor® Q2L series "C-Rated" SIDACtor® device.

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. In addition, we`re doing business all over the world.

Every day, we`re building on our success by making strategic acquisitions, strengthening our customer relationships, and capitalizing on the explosive growth of the Asian market. In all of these efforts, our new brand will play an essential role.
