Abstract:
A surface mounted electrical apparatus, comprising:(1) a thin-board resistive component, which is made of polymer material in which conductive particles are distributed, has a characteristic of positive or negative temperature coefficient, has opposite first and second surfaces, and has opposite first and second end surfaces, 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 component 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 resistive component; (5) a second insulating film, disposed on said second conductive component and extending to the first end surface of said thin-board resistive component; (6) 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 insulating films, and said interconnection via includes a conductive film connected to said metal foils and said first conductive component along the first end surface; and (7) 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 insulating films, and said interconnection via includes a conductive film connected to said metal foils and said second conductive components along the second end surface. conductive components along the second end surface.
