摘要： 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.

摘要： An inductor and method for making the same are provided. The inductor includes a coil formed from a conductor and having a serpentine shape. The coil may have an “S”-shape. The coil has two leads extending from opposite ends of the coil. An inductor body surrounds the coil and portions of the leads. The leads may be wrapped around the body to create contact points on the exterior of the inductor.

摘要： Resistors and a method of manufacturing resistors are described herein. A resistor includes a resistive element and a plurality of conductive elements. The plurality of conductive elements are electrically insulated from one another via a dielectric material and thermally coupled to the resistive element via an adhesive material disposed between each of the plurality of conductive elements and a surface of the resistive element. The plurality of conductive elements is coupled to the resistive element.

摘要： Resistors and a method of manufacturing resistors are described herein. A resistor includes a resistive element and a plurality of upper heat dissipation elements. The plurality of heat dissipation elements are electrically insulated from one another via a dielectric material and thermally coupled to the resistive element via an adhesive material disposed between each of the plurality of heat dissipation elements and a surface of the resistive element. Electrode layers are provided on a bottom surface of the resistive element. Solderable layers form side surfaces of the resistor and assist in thermally coupling the heat dissipation elements, the resistor and the electrode layers.
