Littelfuse

From Precision Fuses to Essential Hardware

Trusted protection for every circuit, from core components to complete solutions

Future Electronics provides a comprehensive selection of Littelfuse circuit protection solutions, including high-quality electronic fuses, Thin Film surface-mount fuses, and accessories. Cartridge fuses in popular formats such as TR5, TE5, and LT5 deliver HBC (High Breaking Capacity) performance with slow-blow characteristics, making them ideal for motors, transformers, and other applications with temporary inrush currents. Part numbers such as 021506.3MXP and 37213150411 exemplify the reliable options available in this category for demanding applications requiring robust overcurrent protection.

Littelfuse Thin Film surface-mount fuses offer fast-acting, precise protection tailored for compact, sensitive electronics where board space is limited. Part numbers like 0468001.NR and 0466.250NR safeguard consumer electronics, telecom equipment, and industrial devices from sudden current spikes, ensuring stable and reliable operation.

Fuses often need holders - and we’ve got you covered! Future Electronics provides a full range of holders, clips, and blocks for secure and flexible installation. Part numbers such as 81600000005 and 01020071Z illustrate the available accessories designed for streamlined integration into electronic systems.
