Agriculture Vehicles
Depend on Littelfuse to deliver dust- and waterproof power distribution modules for agricultural equipment such as tractors and combine harvesters. We also offer battery disconnect switches, dc connectors for tow-behinds, and heavy-duty overcurrent and overvoltage protection devices. Importantly, our engineers lead in developing electronics solutions for EVs used to farm, ranch, and log.
Buses
Optimize performance and protect passengers by choosing Littelfuse electronics solutions for public transit and school buses. Our LED protection devices and driver ICs keep safety lights operating. Our fuses, varistors, and TVS diodes provide reliable circuit protection. We also offer ESD surge suppressors to ensure clear signals for digital cameras and advanced driver assist systems (ADAS).
Construction Vehicles
Properly controlling diesel and electric drive bulldozers, excavators, and mining trucks prevents injuries. Littelfuse enables that by producing durable toggle, push–pull, and ignition switches. We also make dc battery disconnect switches, fuses for circuit protection in maintenance equipment like scissor lifts, and varistors to guard off-highway electronics vehicles against lightning strikes.
Material Handling
Boost the performance of material handling equipment like electric forklifts and automated guided vehicles (AGVs) with electronics solutions from Littelfuse. We make ESD protection for sensors and wireless communication, overcurrent protection devices such as battery terminal fuses, and solid-state relays to manage power efficiently. We also offer inverters to improve EV Li-ion battery charging.
Medium & Heavy-Duty Truck
Injuries occur when dc connectors for tractor-trailers and RVs fail. Littelfuse prevents this by making dependable plugs, sockets, and cables. We also help optimize the performance of medium- and heavy-duty trucks by producing dc power distribution modules and ignition switches. Additionally, our overcurrent and overvoltage protection devices serve well in dump trucks, flatbeds, and tanker trucks.
Passenger Vehicles - Transportation
Our electronics solutions for ICE and electric passenger vehicles include much more than OEM, aftermarket, and custom circuit protection devices. Littelfuse engineers constantly innovate in designing sensors for automatic body, engine, braking, and lighting controls. We also offer cutting-edge products for battery management, dc motors, and components of advanced driver assistance systems (ADAS).
Recreational Vehicles
From ATVs and electric golf carts to towable travel trailer campers and Class A RVs, Littelfuse delivers electronics solutions that make recreational vehicles more reliable, more efficient, and safer. Examples include internationally compliant dc vehicle connectors, waterproof power distribution modules, fuses for overcurrent protection, and varistors for lightning and overvoltage protection.
Specialty Vehicles
Specialty vehicles like fire trucks, ambulances, and garbage trucks require unique electronics solutions beyond fuses for circuit protection and battery disconnect switches to prevent unauthorized operation. For example, Littelfuse makes solenoids that guarantee on-demand performance of emergency vehicle lights. We also offer heavy-duty power distribution modules for critical electrical systems.
