With robust overcurrent protection for 1000 Vdc systems, a compact 5×20 mm design, and exceptional thermal stability, it’s the ideal choice for Battery Management Systems (BMS) and high-voltage DC-DC converters.
Littelfuse, Inc. has introduced its new 823A Series Fuse, an AEC-Q200-qualified, high-voltage surface-mount (SMD) fuse. Designed for automotive applications, this compact 5 x 20 mm fuse offers robust overcurrent protection for 1000 Vdc systems, making it an ideal choice for Battery Management Systems (BMS) and high-voltage DC-DC converters.
The key features include:
- Operates within a wide temperature range of -40°C to 125°C, ensuring reliable performance in extreme conditions.
- High interrupting rating prevents nuisance openings caused by inrush and surge currents, enhancing system protection.
- Compact design optimizes PCB layouts, simplifying integration into modern automotive electronics.
The 823A Series stands out due to its wire-in-air design, which enhances temperature stability and ensures high interrupting ratings of 100 A at 1 kV DC. It features AEC-Q200 qualification, guaranteeing reliability in demanding automotive environments, and its compact footprint helps save valuable PCB space. For design engineers, the 823A Series offers several benefits. Its resilience in high-voltage environments ensures reliable overcurrent protection, making it well-suited for primary circuit protection in automotive applications.
The fuse is particularly useful for critical automotive and industrial applications, including Battery Management Systems (BMS), Battery Disconnect Units (BDU), high-voltage DC-DC converters, and automotive fuel cell cooling systems. As the demand for electric vehicles (EVs) and advanced automotive electronics grows, the 823A Series plays a crucial role in ensuring safety and performance while simplifying design complexity.
Now available in tape and reel format in quantities of 1,000, the 823A Series Fuse can be sourced through authorized Littelfuse distributors worldwide.Daniel Wang, Senior Director of Littelfuse EBU Global Product Management – OC Business, highlighted the innovation behind the 823A Series, stating, “This is the first and only small-size SMD fuse from Littelfuse rated for 1000 Vdc. It provides engineers with a compact, reliable solution for next-generation high-voltage automotive applications.”
