  • Patent number: 9502171
    Abstract: An inductor includes an inductor body having a top surface and a first and second opposite end surfaces. There is a void through the inductor body between the first and second opposite end surfaces. A thermally stable resistive element positioned through the void and turned toward the top surface to forms surface mount terminals which can be used for Kelvin type sensing. Where the inductor body is formed of a ferrite, the inductor body includes a slot. The resistive element may be formed of a punched resistive strip and provide for a partial turn or multiple turns. The inductor may be formed of a distributed gap magnetic material formed around the resistive element. A method for manufacturing the inductor includes positioning an inductor body around a thermally stable resistive element such that terminals of the thermally stable resistive element extend from the inductor body.

  • Publication number: 20160225498
    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.

  • Patent number: 9400294
    Abstract: A current sense resistor and a method of manufacturing a current sensing resistor with temperature coefficient of resistance (TCR) compensation are disclosed. The resistor has a resistive strip disposed between two conductive strips. A pair of main terminals and a pair of voltage sense terminals are formed in the conductive strips. A pair of rough TCR calibration slots is located between the main terminals and the voltage sense terminals, each of the rough TCR calibration slots have a depth selected to obtain a negative starting TCR value observed at the voltage sense terminals. A fine TCR calibration slot is formed between the pair of voltage sense terminals.

  • Patent number: 9396847
    Abstract: A resistor, resistor assembly, and a method of making them are described, with advantages over existing resistors, resistor assemblies, and methods. The resistor includes a helical resistor element wound on an insulator. The insulator has a regularly spaced plurality of teeth on each of two opposite sides, with the helical resistor element situated within the teeth. The insulator provides support for the helical resistor element without use of a separate core within the insulator. The resistor may be assembled by inserting two toothed insulator pieces into a helical resistor element and separating the two insulator pieces such that turns of the helical resistor element are within the teeth of the first and second insulator pieces. Alternatively, the resistor may be assembled by winding a helical resistor element onto a toothed insulator piece.

  • Patent number: 9396849
    Abstract: The present technology is directed toward a resistor and method of manufacturing the resistor. One or more layers of insulative material are formed on a length of resistive material. Portions of the one or more layers insulative material are removed from the resistive material in a pattern based on a predetermined approximate dimension and predetermined approximate resistance value. A first set of one or more conductive layers are formed on the portions of the resistive material exposed by the insulative coating to form a plurality of conductive pads on the resistive material between the patterned insulative material. The sets of conductive pads are probed to measure a preliminary resistance value between the sets of conductive pads.

  • Patent number: 9378872
    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.
