What Are Wirewound Variable Resistors?
Wirewound variable resistors are electrical components made by winding a resistive wire (usually nichrome) around an insulating core. The resistance can be adjusted manually or automatically to regulate current flow, voltage, or power in a circuit.
They are valued for:
High power handling capacity
Excellent temperature stability
Long operational lifespan
Accurate resistance control
These features make them indispensable in high-precision applications where other resistor types, such as carbon or metal film, may not provide sufficient reliability.
