Littelfuse Product Applications

Even the smallest appliances and cordless power tools pack impressively advanced electronics. Robot vacuums require ESD protection to ensure noise-free signals from sensors. Rechargeable drill batteries need solid state relays and overvoltage protectors. From the largest white goods like IoT-enabled commercial refrigerators to one-cup coffeemakers, Littelfuse delivers cutting-edge solutions.

A century of providing circuit protection and power management solutions gives us a deep understanding of how to meet defense and aerospace needs. Our extensive portfolios of high-reliability aviation-specific switches and space-specific connectors withstand the harshest environments. Our integrated engineering, laboratory, and manufacturing group also delivers custom-designed solutions.

Find electronics solutions for new construction, smart building upgrades, and maintenance of electrical, HVAC, safety, and security systems in commercial buildings. As an incomplete list, Littelfuse makes fuses for elevators, varistors and other surge protective devices for lighting and communication systems, magnetic sensors for access control, circuit breaker panels, and parts for GFCI outlets.

As mobile phones, POS systems, and wearables evolve, so do Littelfuse solutions for ESD protection, battery charging, and power management. We offer internationally compliant and custom devices for transient voltage surge suppression and temperature sensing. We also maintain large portfolios of resettable fuses and solid-state relays.

A short circuit, temperature spike, or lightning strike can take datacenter and telecom equipment offline. Littelfuse helps ensure the reliability of cell towers, antennas, base units, and power supplies with fast switching, power factor correction, inverter, rectifier, temperature sensing, and overcurrent, overvoltage, and ESD protection solutions.

Littelfuse’s century of commitment to setting industry standards for automotive circuit protection and powertrain reliability continues as EVs replace fossil-fueled vehicles. From high-voltage fuses for fast-charging stations to dc–dc converters for e-bikes, we offer eMobility electronics solutions for cars, transit, agricultural and construction equipment, and material handling.

Bakeries, breweries, bottlers, meat processors, and wineries seek to maximize productivity and personnel safety. Littelfuse's industrial fuses and GFCIs, surge protective devices, arc flash detectors, shock protection solutions, and motor and pump controllers help achieve those goals. Our devices help protect and boost performance for refrigeration equipment, cookers, mixers, and conveyer belts.

Choosing the right electrical devices for industrial, food processing, and robotics applications reduces downtime and protects people. Littelfuse takes pride in engineering power semiconductors, semiconductor fuses, GFCI solutions, dc disconnect switches, motor and pump controllers, protection relays, control panels, and temperature sensors. We even make fuse pullers to simplify repairs.

Ensuring uptime and on-demand performance by medical equipment and monitors saves lives. Preventing arc flashes from overcurrent events and shocks from electrostatic discharges is equally important for protecting patient and personnel safety. Trust Littelfuse for fuses, overvoltage protection solutions, and ESD suppressors for emergency, diagnostic, and general care devices meeting IEC standards.

Using electrical equipment for mining, drilling, and water treatment creates explosion and shock risks. Littelfuse components engineered to perform optimally despite exposure to dust, moisture, and extreme temperatures can reduce those risks by preventing and controlling arc flashes, electrostatic discharges, faults, and current and voltage surges.

Call it renewable, clean, or green: wind and solar power use will only grow. Littelfuse is keeping pace by producing advanced solutions for battery energy storage systems, photovoltaic panels, solar inverters, and wind turbines. We also make rectifiers, power relays, and overvoltage protection devices for generation, transmission, and storage equipment.

If it has an engine and wheels, Littelfuse makes a circuit breaker, dc disconnect switch, voltage surge suppressor, power distribution module, sensor, and solenoid for it. We invented automotive fuses and perfected resettable PPTC devices. We now lead in engineering electronics solutions for commercial, agricultural, and material-handling EVs. Trust us for OEM, aftermarket, and custom components.

Electric motors, pumps, cables, and switches used on watercraft or dockside cannot degrade or shock users when exposed to water, humidity, or salt. Trust Littelfuse components for applications that demand waterproof or intrinsically safe fuses, relays, circuit breakers, GFCIs, and battery management systems.
