Surface mountable over-current protecting device

A surface mounted electrical apparatus, comprising:

• (A) a first resistive assembly, including:
• (1) thin-board resistive components, each of said components has:
• (a) polymer materials in which conductive particles are distributed;
• (b) a characteristic of positive or negative temperature coefficient;
• (c) opposite first and second surfaces;
• (d) opposite first and second end surfaces, respectively extending from the first surface to the second surface;
• (2) a first conductive component, disposed on the first surface of said thin-board resistive component and extending to the first end surface;
• (3) a second conductive component, disposed on the second surface of said thin-board resistive components and extending to the second end surface;
• (4) a first insulating film, disposed on said first conductive component and extending to the second end surface of said thin-board resistance component;
• (5) a second insulating film disposed on the second conductive component and extending to the first end surface of said thin-board resistive component;
• (B) at least one second resistive assembly of the same structure as said first resistive assembly and superimposed on said first resistive assembly;
• (C) a first electrode, including a main body and an interconnection via, wherein said main body includes a pair of metal foils disposed on said first and second resistive assemblies and said interconnection via includes a conductive film coupled with said metal foils and said first conductive components along the first end surface;
• and
• (D) a second electrode, including a main body and an interconnection via, wherein said main body includes a pair of metal foils disposed on said first and second resistive assemblies;
• said interconnection via includes a conductive film coupled as with said metal foils and said second conductive components along the second end surface.
