The 881 series NANO2® fuse is a relatively small, surface-mount fuse which provides over-current protection for applications operating at high current values in a limited space.

Such applications are mostly served today through the use of a single, large industrial fuse with a high current rating.

In some cases, designers may implement over- current protection with a parallel configuration of multiple lower-current surface-mount fuses.

The 881 series fuses can replace either of these solutions with a single, compact fuse which offers a high level of protection up to 100A, and which occupies less board space. The surface-mount 881 devices have a 12.5mm x 10mm footprint, and are just 6.8mm high.

Resistant to the effects of temperature cycling and vibration, the 881 series fuses also help users to satisfy strict reliability requirements in end-product designs.
