Surface mountable Nano2® 485 Series Fuse combines exceptional overcurrent protection for high voltage DC circuits with a space-saving footprint.

The Nano2® 485 Series Fuse from Littelfuse is a compact,  surface mountable 600VDC fuse for overcurrent protection of high voltage DC circuits. The 485 Series Fuse packs a high voltage and energy protection of high voltage DC circuits. The 485 Series Fuse packs a high voltage and energy protection capability in a very small footprint. It provides fast-acting blow characteristics to ensure high-speed protection against surge currents and overload conditions. A ceramic housing ensures robust operation and long-term reliability, even in high ambient operating temperatures. The 485 Series Fuse offers circuit designers a more compact, more cost-competitive alternative to traditional larger, through-hole-type 600VDC fuses for creating cost-effective designs in accordance with the industry trend for surface mount designs.
