Wire-wound resistors are electrical components made by winding a metal wire around a ceramic or plastic core. This design allows them to handle higher power levels and provide precise resistance values. They are commonly used in applications where accuracy and stability are essential, such as in audio equipment and power supplies. These resistors come in various resistance values and power ratings, making them versatile for different electronic circuits. However, they can be larger and more expensive than other types of resistors, like carbon film or metal film resistors, which may be more suitable for low-power applications.
