ABSTRACT:
A current protection device comprises a substrate having an upper portion and a lower portion; a fusing layer installed between the upper portion and the lower portion; ends of the fusing layer exposed from the substrate; a cavity formed near surfaces of the fusing layer for providing a space to receive the fusing layer as the fusing layer fuses; and an end electrode having three layers including a silver thin layer, a nickel thin layer and a tin thin layer; the end electrode being formed as a conductive electrode. The method for forming the same is provided.
