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.

443 250V Nano²® Fuses

Littelfuse 443 250V Nano²® Fuses are time-lag, surface-mount devices designed to support higher voltage applications that have limited space. These fuses enable compliance with the RoHS directive. They are fully compatible with lead-free solder alloy and higher temperature profiles associated with lead-free assembly. Littelfuse 250V Nano² Fuses are available in ratings of 0.50A to 5.0A. The 443 series is ideal for use in a variety of applications, including AC/DC power adapters, telecom equipment system power applications, portable system built-in AC/DC converters, high voltage DC/DC converters, and lighting systems.

Intelligent Outlet Solutions

Littelfuse Intelligent Outlet Solutions components feature smart outlets and light dimmers that can be controlled via apps or virtual assistants. The Littelfuse product line includes PICO® II 473 Slo-Blo® Fuses, UltraMOV 14mm Varistors, SJ SCR Switching Thyristors, Thyristor Triacs, IX4340 Gate Drivers, and 650V X2 MOSFETs. The intelligent outlets plug into or replace traditional outlets and allow users to control what is plugged into them through an app or virtual assistant. The smart light dimmers are also remotely controlled. Instead of diverting energy from the light bulb into a resistor, the modern light bulb circuit is switched off many times per second around the fluctuation of household alternating current for efficiency.

NANO Fuses

Littelfuse NANO® Fuses are fast-acting, high-performance fuses available in a wide range of available current ratings. The portfolio includes 448 NANO2® SMF Fuses, which are fast-acting fuses available in current ratings from 62mA to 15A. The 443 NANO2 series features square surface-mount, time-lag devices with a 250VAC voltage rating. Littelfuse 449 NANO2 Slo-Blo® Fuses offer enhanced inrush withstand characteristics over NANO2 Fast-Acting Fuses. The 456 series is designed to support higher current requirements and is fully compatible with lead-free solder alloys. Littelfuse 456 fuses are ideal for storage system powers, cooling fan systems for PC servers, and base station power supplies. Littelfuse NANO Fuses include additional series as well.
