New Littelfuse 823A Series Fuse Offers Compact 1000Vdc Protection for Electric Vehicles

Littelfuse has introduced the 823A Series Fuse, a compact, high-voltage surface-mount fuse designed to meet the increasing power demands of modern automotive electronics. This small but powerful fuse is AEC Q200 qualified and built for high-voltage applications, making it a great fit for electric vehicles and other advanced automotive systems. 

It can handle high voltages up to 1000 Vdc while keeping circuits safe. What makes the 823A Series stand out is its 5 x 20 mm footprint, which allows engineers to save space while ensuring strong overcurrent protection. The 823A Series Fuse uses a smart wire-in-air design, which helps it handle heat better and stay stable even in tough conditions. It also offers strong protection with a high interrupting rating (100A at 1kV DC) and can absorb more energy before breaking, all while staying compact and space-efficient.
