A resistor is a two-terminal electrical component that offers resistance to the flow of electric current. Power resistors, variable resistors, chip resistors, and power chip resistors have numerous applications in electronic circuits. High-voltage variable resistors are generally used for adjusting focus voltages and screen voltages in television receivers. Shunt resistors are used to measure high currents, they are measuring resistors which are connected in series with the component to be measured. Power resistors in many electric motor applications are used as braking loads for the motors. In frequency converters, power resistors are used in snubber circuits that protect high-power switching devices by suppressing voltage and current spikes arising from line switching actions. A semiconductor resistor typically comprises a body portion formed of a material having a predetermined resistivity, often stated in units of ohms per square, associated therewith. Electrical connection to the body portion is generally provided by a plurality of metal contacts formed at opposite ends of the resistor body. The contacts at the ends of the resistor body may be connected to metal terminals for providing electrical interconnection with other components and/or structures in the IC device.
