Vehicle Communication Solutions

Littelfuse Vehicle Communication Solutions protects the on-board power and communication circuitry responsible for V2V (vehicle-to-vehicle) and V2I (vehicle-to-infrastructure) communication. ESD, surge, and overcurrents threaten these systems' ability to share real-time data (speed, direction, location, etc.) with other vehicles as well as traffic lights and smart roads. Littelfuse produces a line of fuses, PPTCs, TVS diodes and diode arrays, MLVs, and polymer ESD suppressors to help ensure operational uptime of these systems.
