Vision. Innovation. Entrepreneurial Spirit. These key traits are what drove Edward V. Sundt to sell his car to raise initial capital for what became Littelfuse Laboratories in 1927. Those founding principles—and a dedicated team of engineers, operators, and professionals—are committed to taking Littelfuse into the future as the leading manufacturer of a sustainable, connected, and safer world.

Littelfuse components enable efficient switching, precise control, and robust circuit protection in power tool design. Explore our Power Tools application page to learn more.
