A wirewound resistor is a type of electrical component used to limit the flow of current in a circuit. It is made by winding a metal wire, usually made of materials like nickel-chromium or copper-nickel, around a ceramic or insulating core. This design allows for precise resistance values and can handle higher power ratings compared to other resistor types. These resistors are commonly used in applications requiring high accuracy and stability, such as in audio equipment and power supplies. Their construction provides excellent thermal stability, making them suitable for environments with varying temperatures.
