Consumer Drone Systems

Littelfuse Consumer Drone Systems offer solutions for battery chargers, battery systems, and payload systems. These systems provide Schottky diodes for output rectification/reverse blocking, TVS diodes for secondary protection against voltage transients, and fuses to protect the power stage from overcurrent. The systems offer USB-C® for consumer drones with a 5V to 48V range and up to 240W (typical 100W to 140W), and provide battery protection for <60V. Typical applications include photography/video, FPV racing, and recreational flying.

Remote Control Systems

Littelfuse Remote Control Systems offer solutions for load switching, joysticks, on/off switches, and USB protection. These systems provide the protection IC (eFuse) with USB-C® for overcurrent, overvoltage, and short-circuit protection for USB input. The remote control systems also provide a TVS diode array for ESD protection of the USB data lines (high-speed interface). These systems support power on/off, mode selection, user interface input, and joystick input/directional control for Unmanned Aerial Vehicle (UAV) operation. The remote control systems offer load switch ICs for power distribution control, subsystem on/off switching, and battery load management. Typical applications include ISR, military, border surveillance, agriculture, delivery/logistics, inspection, and public safety.

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.

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.

Fuel-Powered/Hybrid Military UAV Systems

Littelfuse Fuel-Powered/Hybrid Military Unmanned Aerial Vehicle (UAV) Systems offer solutions for power conversion and DC bus, power distribution, and charger/ground power. These systems support power conversion and a DC bus with a rectifier diode that converts AC line voltage to DC. The fuel-powered/hybrid military Unmanned Aerial Vehicle (UAV) systems provide TVS diodes, fuses, and MOSFETs for semiconductor switches, surge protection, and rectification. These systems offer AEC-Q/MIL-grade products across various functions. Typical applications include Intelligence, Surveillance, and Reconnaissance (ISR), military, and border surveillance.

Electric Bike (e-Bikes) Solutions

Littelfuse provides a wide portfolio of products suitable for electric bike applications, including switches, fuses, and diodes. Many battery-powered devices in various applications share similar safety and control elements, such as cleaning equipment, construction tools, garden tools, and power tools. Littelfuse e-Bike solutions can be used for motor drive and comfort units and displays.

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.

KSC Sealed Tact Switches for SMT

C&K Switches KSC Series Sealed Tact Switches for SMT are ultra-long life switches designed to withstand intensive use and last up to 5 million cycles. The silicon actuators facilitate switch integration and provide possible pre-travel and post-travel depending on force and actuator hardness. The switches best match applications such as elevator and joystick buttons that require resistant switches. The KSC Series exist in both J bend and Gullwing versions to better fit the chosen soldering process.
