  • Patent number: 6181234
    Abstract: A monolithic resistor is provided with a central resistive metallic foil strip positioned between and attached to a pair of wings formed from an electrically conductive metallic foil. The wings include large surface areas to dissipate heat. A plurality of terminal pins are formed in the conductive strips for connection to an integrated circuit board, as well as a current source.

  • Patent number: 5999085
    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.
