Wirewound resistors are electrical components made by winding a metal wire around a ceramic or insulating core. This design allows them to achieve high precision and stability in resistance values. They are commonly used in applications where accuracy is crucial, such as in measuring instruments and power supplies. These resistors can handle higher power levels compared to other types, making them suitable for demanding environments. However, they may have a higher inductance, which can affect performance in high-frequency applications. Overall, wirewound resistors are valued for their reliability and durability in various electronic circuits.
