85 Years of Innovation and Engineering Expertise

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.

    Littelfuse has a great culture of transparency and openness. The Executive team has helped keep the company financially stable and strong with good strategic vision. Littelfuse is a high performance organization and you are surrounded by very talented peers when you work here.


    As Littelfuse is very cost conscious, the resources are somewhat limited, although this is getting better lately as the company grows. Along the same lines, there are ample opportunities to contribute with this lean organization.

    IT Interview

    Anonymous Employee in Des Plaines, IL
    Application Details

    I applied through a recruiter. The process took 2 weeks - interviewed at Littelfuse in February 2011.

    Interview Details

    I was contacted by a headhunter and they said that I was a perfect match and the salary was within my requirements. I did a phone interview with the hiring manager which went well and a second 1:1 interview was scheduled with him, other managers and a team member. That went very well too and I was told by the headhunter that everything did do well and that an offer will come in a day or so. I was then told I needed to go through their HR person and take two online tests, IQ and personality. I talked with their HR person which wanted to know exactly how much I was looking for and OPEN was not an option, putting me on the spot. You never give and exact amount and when you are dealing with a headhunter you are not suppose to discuss salary with HR. The headhunters will tell you to never give an exact amount because you may lowball yourself or price yourself out and ruin the deal for the headhunter. I did give a salary amount and took the two tests. After that, nothing, silence. I did not get anything from anyone, not even the headhunter. I heard from friends that the personality test has no wrong answers but if you do not answer subjective questions the way they answered them then you are sunk, no explanation is necessary. I would expect to hear something as a professional courtesy.
