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.
