Motor Control Solutions

Littelfuse Motor Control Solutions provide protections that are critical to a vehicle's overall reliability. As mechanical/hydraulic actuators are replaced with electric motors, load dumps, overcurrents, surges, and ESD become potential threats. Littelfuse offers a wide range of TVS Diodes and Diode Arrays, MLVs, MOVs, and PPTCs to protect motor control applications.
