Every day, we're building on our success by developing innovative products, strengthening our customer relationships, making strategic acquisitions and capitalizing on growing markets around the world.

Our latest acquisition positions our business for continued success and growth, strengthening our position as an industry leader in circuit protection. By addressing product gaps in two highly technical target markets, battery management and automotive electronics, we will lead the way in the field of PPTC (polymeric positive temperature coefficient) products. The strength of the acquired circuit protection devices business in PPTCs complements the strength Littelfuse has in fuse technologies and enables us to offer a more comprehensive suite of products to customers.

Added Product Technologies
Expanded Global Reach

In Japan, we have gained a strong team and customer base as well as a manufacturing facility. Our expansion in China will complement and strengthen our current team and facilities.

Transition to Littelfuse

There will be benefits for both Littelfuse and customers in the future; a full integration will take some time. In the short term, we anticipate that you will experience little, if any, immediate change in your business interactions. [For all countries except Italy and Spain] You will continue to work with the same sales and customer service teams you do today, be invoiced in generally the same manner and receive the same products. When and if changes do occur, we are fully committed to making the transition as seamless for you as possible.  As we look to the future, we are enthusiastic about the opportunities to come.
