Commercial & Tactical UAV Systems

Littelfuse Commercial and Tactical Unmanned Aerial Vehicle (UAV) Systems offer solutions for Li-Ion battery protection, battery chargers, and power distribution. These systems provide fuses for input protection/overcurrent protection, MOSFETs for semiconductor switching, and TVS diodes for DC output transient/surge protection. The commercial and tactical UAV systems offer battery protection >60V and provide main-pack fault isolation, battery disconnect/power path control (pre-charge support), and branch circuit overcurrent protection. Typical applications include Intelligence, Surveillance, and Reconnaissance (ISR), military, border surveillance, agriculture, delivery/logistics, inspection, and public safety.

Indoor LED Lighting Circuit Protection

Littelfuse Indoor LED Lighting Circuit Protection ensures a long operating life, increased energy efficiency, and safety. LEDs can be damaged by voltage or current surges, and by extreme temperatures. Littelfuse circuit protection technology protects LED assemblies from potential damage. Important circuit protection technologies include metal-oxide varistors (MOVs), transient voltage suppression (TVS) diodes, and fuses.

1812L POLY-FUSE® PTC Resettable Fuses

Littelfuse 1812L POLY-FUSE® PTC Resettable Fuses provide overcurrent protection for applications where resettable protection is desired. The compact fuses offer fast response time to fault currents and feature low resistance. Littelfuse 1812L POLY-FUSE PTC Resettable Fuses applications include plug-and-play protection for motherboards and peripherals, USB peripherals, PCI cards, and game console port protection.

Drone Subsystems

Littelfuse Drone Subsystems offer solutions for USB-C PD and Li-ion battery chargers, battery pack systems, and BLDC motors. These subsystems offer fuses for various functions, including AC input overcurrent protection and fault isolation, protection of the battery and downstream controller, pack, wiring, and controller. The drone subsystems provide TVS diodes for primary-side switching transient suppression and cell monitor IC sense line input overvoltage protection. These subsystems are appropriate for various drones, including toy, camera, First-Person View (FPV), enterprise, industrial, Intelligence, Surveillance, and Reconnaissance (ISR), inspection/mapping, agriculture, and heavy lift. Typical applications include delivery/logistics, public safety, border surveillance, and military.

PolySwitch Surface-Mount Resettable PTCs

Littelfuse PolySwitch Surface-Mount (SMD) Resettable PTCs provide overcurrent protection for applications where space is at a premium, and resettable protection is desired. The components are reliable and capable of protecting computers and consumer electronics against temporary overcurrent faults. Package sizes range from 0402 to 3425, while the current hold ranges from 50mA to 7.0A. The Littelfuse PolySwitch SMD product family is qualified to strict automotive standards (per AECQ200). As a result, these PTCs are suitable for protecting electronic control units (ECUs) against damage from faults that would otherwise require costly, complete module replacement.

IT Rack & Server Tray Solutions

Littelfuse IT Rack and Server Tray Solutions support the safe and efficient transfer of electrical energy throughout modern data center and compute rack architectures. The portfolio addresses evolving power delivery requirements across AC-powered and native DC-powered environments, including IT racks, server trays, battery backup systems, power distribution units, hot-swap circuits, and high-voltage power racks. Solutions span circuit protection, power semiconductors, sensing, switching, and control technologies, enabling reliable power delivery from grid infrastructure to computing hardware. Littelfuse Power Rack Solutions address enterprise computing, AI infrastructure, networking systems, storage platforms, battery backup units, server power distribution, power shelves, and hot-swap subsystems.

PolySwitch Resettable Devices

Littelfuse PolySwitch and POLY-FUSE Devices are Polymeric Positive Temperature Coefficient (PPTC) devices that offer a resettable overcurrent protection alternative, reducing warranty, service, and repair costs. PTCs increase resistance as temperature increases due to increased flow. The components are designed to limit unsafe currents while allowing constant safe current levels, resistance will "reset" automatically when the fault is removed, and temperature returns to safe levels. The ability of the PTCs to reset themselves after exposure to a fault current makes them ideal within circuits that are not easily accessible. PTCs are typically used as circuit protection in applications where sensitive components are at constant risk of damage from overcurrent conditions. The components are also ideal for situations where frequent overcurrent conditions occur or constant uptime is required. Littelfuse Resettable PTCs (PPTCs) are typically used in consumer electronics, power line, telecom, I/O port, process control and medical equipment protection applications.
