  • 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: 6510605
    Abstract: A surface mount resistor is formed from an elongated resistive body having first and second terminal ends and a raised center portion formed therebetween. The raised center portion includes slots in its edges which form a serpentine current path through the raised center portion of the resistor. A dielectric surrounds and encapsulates the raised center portion and an electrically conductive material coats the first and second terminal ends. The method for manufacturing involves utilizing an elongated ribbon which is of unitary construction and which is formed to create a carrier strip and a raised center portion for the resistors ultimately to be formed.

  • Patent number: 6184775
    Abstract: An improved surface mount resistor and method for making the same includes a body comprised of an elongated strip of electrically resistive material and a resistor terminal formed at each end of the resistive material. The resistive material is machined with a laser beam to create a current path having a desired resistance. The pattern cut is determined by partitioning the resistive material into a plurality of squares forming a current path through the resistive material with the correct resistivity. The resistive material is cut primarily with axial cuts so that the beam strength of the resistive material is maintained.

  • Patent number: RE39660
    Abstract: An electrical resistor has a surface mounted four terminal current sensor of a very low resistance value and capable of handling short pulses of high power. It comprises a flat metal late, 1 to 50 mils thick, of an alloy of high electrical resistivity, to which are welded, on two opposite sides, two flat metal plates of very high electrical conductivity which serve as terminations for electrical interconnection. A slot is cut, from the outside edge toward the center, into each of the two termination plates which divides them into a wide pad for connection of current carrying wires and a narrow one for voltage sensing. The depth of the slots is optimized to get the best stability of resistance readings with changing ambient temperature and under influence of the self-heating effect.
