Littelfuse, announced the NANO2 Surface-Mount 708 Series Fuse, the first surface-mount fuse offering a 14,000 A interrupting rating at 80 VDC. The 708 Series is engineered for next-generation 48 VDC power architectures in AI servers, hyperscale data centers, and high-density power distribution systems. It provides current ratings from 60 A to 200 A in a compact surface-mount package as an alternative to larger through-hole or bolt-down fuses.
The new fuse supports automated assembly processes and enables space savings in high-density designs while delivering high pulse resistance and compliance with global safety standards.
“With this new fuse our first Littelfuse surface-mount fuse to deliver a 14,000 A interrupt rating at 80 VDC we’re giving designers using legacy through-hole or bolt-down solutions a path to transition to surface-mount technology,” said Daniel Wang, Senior Director of Product Management, Over Current–Passives, at Littelfuse. “That shift enables automated manufacturing, improves productivity, and reduces overall system cost.”
Key applications include supplemental overcurrent protection for power distribution units (PDUs), power shelves, battery backup units (BBUs), power supply units (PSUs), renewable energy systems, and battery management systems (BMS).
The 708 Series forms part of Littelfuse’s broader portfolio of 48 V protection solutions for data center infrastructure, alongside the 456, 871, and 881 Series.
The fuses are available in tape-and-reel packaging in quantities of 500 through authorized Littelfuse distributors worldwide.
