LED Lighting Solutions

Littelfuse LED Lighting Solutions support all facets of the LED lighting market with innovative solutions that not only meet regulatory standards but also increase equipment safety and reliability. To help protect end-users, Littelfuse works closely with many LED driver IC suppliers, to ensure their evaluation boards and reference designs comply with safety and surge immunity requirements. They also assist LED lighting power supply manufacturers in designing optimal protection schemes for their driver modules. At the OEM level, they cooperate with luminaire and lamp manufacturers to ensure their products are optimally designed for robust surge immunity protection.

Radial-Leaded PolySwitch Resettable PPTCs

Littelfuse Radial-Leaded Resettable PPTCs are designed to provide overcurrent protection for applications where space is not a concern, and resettable protection is preferred. With so many options in the radial-leaded PPTCs family, engineers can design with more flexibility. The components feature current ratings from 50mA to 15A, low resistance, and a fast time-to-trip. Higher voltage ratings (6V to 72V) allow for use in new applications. Littelfuse Radial-Leaded Resettable PPTCs are compatible with high-volume electronics assembly and can assist in meeting regulatory requirements.

Motor Control Solutions

Littelfuse Motor Control Solutions provide protections that are critical to a vehicle's overall reliability. As mechanical/hydraulic actuators are replaced with electric motors, load dumps, overcurrents, surges, and ESD become potential threats. Littelfuse offers a wide range of TVS Diodes and Diode Arrays, MLVs, MOVs, and PPTCs to protect motor control applications.

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.

Automotive Application Solutions

Littelfuse Automotive Solutions contain a portfolio of AEC-Q101 and AEC-Q200 qualified TVS diodes, diode arrays, varistors, multilayer varistors, and POLY-FUSE® PTCs. Each new generation of vehicles has an increased number of electronics that control everything from the radio to fuel injection. Littelfuse provides circuit protection solutions for a range of difficult automotive applications.
