Abstract
An over-current protection device includes a conductive composite having a first crystalline fluorinated polymer, a plurality of particulates, a conductive filler, and a non-conductive filler, wherein the plurality of particulates include a second crystalline fluorinated polymer. The first crystalline fluorinated polymer has a crystalline melting temperature of between 150 and 190 degrees Celsius. The plurality of particulates including the second crystalline fluorinated polymer are disposed in the conductive composite, having a crystalline melting temperature of between 320 and 390 degrees Celsius and having a particulate diameter of from 1 to 50 micrometers. The conductive filler and the non-conductive filler are dispersed in the conductive composite.
