  • Publication number: 20180047539
    Abstract: Provided are a fuse resistor and a method of manufacturing the same, more particularly, are a fuse resistor mounted at an electric circuit of an electronic product to prevent the electronic product from breaking down due to inrush current, increase of internal temperature, and continuous overcurrent, and a method of manufacturing the same. The fuse resistor is capable of simplifying an assembly process by coupling a thermal fuse and a lead wire in a modularized manner and by fixing a fusing lead wire to the lead wire in an integrated manner to form a lower molding unit, and a method of manufacturing the same. The fuse resistor has a simple structure and is capable of being miniaturized as an integrated structure of the thermal fuse and the lead wire is inserted, and a method of manufacturing the same.

  • Patent number: 9697969
    Abstract: Disclosed is a fuse resistor provided on an electrical circuit to protect the electrical circuit and elements. The fuse resistor includes a substrate on which first and second resistive terminals and fuse terminals are formed, first and second resistive elements surface-mounted on the first and second resistive terminals and dividing applied current or voltage, and a temperature fuse surface-mounted on the fuse terminals and broken by heat generated from the first and second resistive elements. If overcurrent or overvoltage is applied, the first and second resistive elements generate heat and the temperature fuse is broken by the generated heat.
