The 881F Series NANO²® fuse is a relatively small sized, high-current, surface-mount fuse which provides overcurrent protection for applications of high operating current in a limited space. This is the faster opening version of the original 881 Series which offers faster opening response during current overload conditions, protecting downstream components from getting damaged.

Such applications are mostly served today through a single large-sized high-current industrial type fuse or in some cases, parallel configuration of lower amperage SMD fuses.

The 881F Series fuses provide the option of a single fuse solution for protection for such application requirements.
