WebThese resistors are made by wrapped a high-performance resistive alloy wire around a low thermal resistance ceramic core. Wirewound resistors have superior pulse capability and available in non-inductive styles as well. W, WS and FW series axial leaded through hole wirewound resistors are coated by UL 94V-0 compliant material. WebResistive wire is wound around an insulating ceramic core and the wiper slides over the windings. Rheostats were often used as power control devices, for example to control light intensity (dimmer), speed of motors, heaters, and ovens. They are not typically used for this function anymore. This is because of their relatively low efficiency. Web19 aug. 2024 · A wire-wound resistor is another type of resistor produced by winding an insulating core or rod around a resistive wire. These types of resistor are made of an insulated metal wire coiled around a non-conductive core made of ceramic, plastic, or glass. Metal wires are often made of extremely resistant alloys such as nichrome or Manganin. joy and ralph ellis
