Littelfuse 881 Series Nano2 Surface Mount Fuses

Littelfuse 881 Series Nano2 High Current Subminiature Surface Mount Fuses are small-sized, square, surface-mount fuses that provide over-current protection for applications of high operating current in a limited space. These high-current fuses offer a single fuse solution for protection, enhanced reliability, and power efficiency by optimizing thermal performance and minimizing power loss. The 881 series are available in amperage ratings from 60A to 125A in a small footprint and operate from -55°C to +100°C temperature range. These fuses guarantee protection against overload and short circuit events and their relatively high interrupting rating suits a wide variety of applications.
