  • Patent number: 6901655
    Abstract: A surface mount resistor includes an elongated piece of resistive material having strips of conductive material attached to its opposite ends. The strips of conductive material are separated to create an exposed central portion of the resistive material therebetween. According to the method the resistive strip is attached to a single co extensive strip of conductive material and a central portion of the conductive material is removed to create the exposed central portion of the resistive strip.

  • Publication number: 20040233032
    Abstract: A high power resistor includes a resistance element with first and second leads extending out from the opposite ends thereof. A heat sink of dielectric material is in heat conducting relation to the resistance element. The heat conducting relationship of the resistance element and the heat sink render the resistance element capable of operating as a resistor between the temperatures of −65° C. to +275° C. The heat sink is adhered to the resistance element and a molding compound is molded around the resistance 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: 6460244
    Abstract: A method for making a high current, low profile inductor includes a wire coil having an inter coil end and an outer coil end. A magnetic material completely surrounds the wire coil to form an inductor body. First and second leads connected to the inner coil end and the outer coil end respectively extend through the magnetic material to the exterior of the inductor body. The method of operation involves pressure molding the magnetic material around the wire coil.

  • Patent number: 6449829
    Abstract: method for making a high current, low profile inductor includes taking an elongated plate, cutting a plurality of slots in the sides of the plate so as to form a plurality of cross segments extending transversely with respect to the length of the plate and a plurality of connecting segments extending approximately axially with respect to the longitudinal axis of the plate. The method further requires bending the segments transversely with respect to the plate axis so as to place the opposite flat surfaces of the cross segments in planes parallel to one another and facing in an axial direction with respect to the longitudinal plate axis.

  • Patent number: 6391526
    Abstract: A thick film low value high frequency inductor made by the process of subjecting a conductor layer to a plurality of linear cuts by a pulsing laser cutter imposed simultaneously on the entire length of the linear cut being made to create a cross sectional cut of substantial rectangular configuration. The conductor body is a layer of dried silver thick film ink. The method of making a thick film low value high frequency inductor involves the steps of taking a conductor layer comprised of a dried layer of photo sensitive silver ink, masking the ink with the negative of the desired configuration of the ink, exposing the ink to UV radiation, developing the ink, and firing the layer to adhere the silver to the layer.
