  • Patent number: 10147524
    Abstract: A resistor includes a substantially cylindrical resistive element having a resistance of less than about 1 m?, a substantially cylindrical first termination electrically connected to the resistive element and a second termination electrically connected to the resistive element. The substantially cylindrical first termination is hollow to allow for accepting a connection such as from a battery cable. In addition there may be sense leads present on the resistor. A method of forming a substantially cylindrical resistor includes forming a hollow cylindrical resistor body by rolling a flat sheet comprising a resistive element and a first termination and a second termination joined on opposite ends of the resistive element.

  • Patent number: 9916921
    Abstract: A metal strip resistor is provided. The metal strip resistor includes a metal strip forming a resistive element and providing support for the metal strip resistor without use of a separate substrate. There are first and second opposite terminations overlaying the metal strip. There is plating on each of the first and second opposite terminations. There is also an insulating material overlaying the metal strip between the first and second opposite terminations. A method for forming a metal strip resistor wherein a metal strip provides support for the metal strip resistor without use of a separate substrate is provided. The method includes coating an insulative material to the metal strip, applying a lithographic process to form a conductive pattern overlaying the resistive material wherein the conductive pattern includes first and second opposite terminations, electroplating the conductive pattern, and adjusting resistance of the metal strip.
