  • Method of making non-inductive cylindrical thin film resistor
    Patent number: 4268954
    Abstract: A thin film, cylindrical resistor is disclosed which exhibits non-inductive characteristics and which may be fabricated easily and economically. A cylindrical insulative substrate is provided with electrically conductive termination bands and a thin coating of electrically resistive material over the entire cylindrical surface. The resistive material is then cut along an axial path and along an interrupted spiral path so as to form the resistive material into a serpentine path along the cylindrical substrate. Leads are attached to each end and as the current traverses the length of the cylinder it travels in a serpentine path. The current travels in opposite directions along adjacent parallel portions of the path thereby cancelling out the major portion of inductance.
    Type: Grant
    Filed: March 2, 1979
    Date of Patent: May 26, 1981
    Assignee: Angstrohm Precision Incorporated
    Inventors: D. Lamar Sease, Benjamin Solow, Eduard F. Boeckmann, David Rabinow
