At Littelfuse, we continue to build on our success by developing innovative products, strengthening our customer relationships, making strategic acquisitions and capitalizing on growing markets around the world.

Our acquisition of U.S. Sensor Corporation’s assets positions our business for continued success and growth, and expands our sensor portfolio with thermistors and probe assemblies used in the most demanding temperature sensing applications for the electronics and industrial markets. In addition, the acquired business brings strong design capabilities that complement our growth initiatives.
