Surface mountable electrical device

摘要

A surface mountable electrical devices includes a laminate body having a plurality of stacked PTC sheets, two overlapping metal foil sheets sandwiched between two adjacent ones of the PTC sheets, a conductive first electrode layer, a conductive second electrode layer spaced apart from the first electrode layer, and a conductive third electrode layer. The two adjacent ones of the PTC sheets have contact faces with inlaid portions respectively inlaid with the metal foil sheets and non-inlaid portions bonded to each other. At least a conductive transverse layer interconnects the first and third electrode layers and the metal foil sheets.
