Protection element

Abstract

Disclosed is a protection element having electrodes for electrically connecting an external circuit, and a fuse structure formed by stacking at least two metal layers of different melting points and installed between the at least two electrodes. The fusing temperature of the fuse structure can be adjusted by controlling the mass ratio of the two different metal layers, and such design not just offers more diversified product specifications to the protection element only, but also provides a broader range of selecting the metals to avoid metals that produce toxic substances, so as to help passing the RoHS standard of the protection element.
