NANO²® High-Current Subminiature Fuse – 456SD Series

Littelfuse’s small sized, surface-mountable high-current fuse provides surge current protection.

Littelfuse’s 456SD series NANO² fuse is a small sized, surface-mountable high-current fuse which provides over current and excessive surge current protection for applications operating at high current in a limited space.

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 456SD 50 A series fuse gives the option of a single fuse solution for protection for such application requirements.

Features
