Abstract: A fuse and a manufacturing method thereof are disclosed. Since a nonconductive member formed of a ceramic material with excellent mechanical strength and a ceramic tube are used and the ceramic tube is joined to sealing electrodes by use of brazing rings, durability of the fuse is considerably improved. The fuse may be stably used at a high voltage by improving time-lag characteristics.

Abstract: Disclosed is a complex protection device including a substrate, fuse terminals provided on the substrate, first resistive terminals provided on the substrate so as to be separated from the fuse terminals, second resistive terminals provided on the substrate opposite to the first resistive terminals across the fuse terminals, a fusible element connected to the fuse terminals, a first surface-mounted resistive element connected to the first resistive terminals, a second surface-mounted resistive element connected to the second resistive terminals, at least one printed resistive element connected to at least one of the first resistive terminals and the second resistive terminals and connected to at least one of the first surface-mounted resistive element and the second surface-mounted resistive element, and a switching element controlling flow of current to the first and second surface-mounted resistive elements and the at least one printed resistive element if overvoltage is applied.
