The self recovery fuse is a kind of over current electronic protection element. The polymer organic polymer is mixed with conductive particle material under the condition of high pressure, high temperature and vulcanization, and it is processed by special process. It's customary to call PPTC (PolyerPositiveTemperature Coefficent) self recovery fuse. Strictly speaking, PPTC is not self restoring fuse, ResettableFuse is self restoring fuse.
