, features a wire coil wound around a ceramic or fiberglass core, which is then housed in an aluminum casing. This casing provides mechanical protection and acts as a heat sink to dissipate heat generated during operation.
Wirewound resistors are known for their high precision and accuracy. The wire coil used in these resistors has a low temperature coefficient of resistance, meaning its resistance remains relatively stable across a wide temperature range. This makes them suitable for applications where temperature changes can affect the performance of the circuit.
