摘要： A high power resistor (10) includes a resistance element (38), with first and second leads (24, 26) extending out from the opposite ends thereof. A heat sink (56) 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 DEG C to +275 DEG C. The heat sink is adhered to the resistance element and a molding compound (58) is molded around the resistance element.

摘要： A flux-channeled high current inductor (30) includes an inductor body (12, 14) having a first end and an opposite second end and a conductor (32, 34) extending through the inductor body. The conductor includes a plurality of separate channels through a cross-sectional area of the inductor body thereby directing magnetic flux (50, 52, 54, 56) inducted by a current (36, 40) flowing through the conductor into two or more cross-sectional areas and reducing flux density of a given single area. The inductor body may be formed of a first ferromagnetic plate (12) and a second ferromagnetic plate (14). The inductor may be formed from a single component magnetic core and have one or more slits (16) to define inductance. The inductor may be formed of a magnetic powder. A method is provided for manufacturing flux-channeled high current inductors.

摘要： 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.

摘要： A resistor includes a substantially cylindrical resistive element (12) having a resistance of less than about 1 mOhm, a substantially cylindrical first terminal (18) electrically connected to the resistive element and a second terminal (20) electrically connected to the resistive element. The substantially cylindrical first terminal is hollow to allow for accepting a connection such as from a battery cable or a battery post (30). In addition there may be sense leads (22, 24) 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.

摘要： An integrated assembly includes a resistor and a heat spreader. The resistor includes a resistive element and terminals. The heat spreader is integrated with the resistor and includes a heat sink of thermally conducting and electrically insulating material and terminations of a thermally conducting material and situated at an edge of the heat sink. At least a portion of a top surface of the resistive element is in thermally conductive contact with the heat sink. Each resistor terminal is in thermally conductive contact with a corresponding termination of the heat sink. A method of fabricating an integrated assembly of a resistor and a heat spreader includes forming the heat spreader, forming the resistor, and joining the heat spreader to the resistor by bonding at least a portion of a top surface of the resistive element to the heat sink and bonding each electrically conducting terminal to a corresponding termination.
