Wirewound Resistor is a kind of resistor made by winding metal wires or alloy wires. It plays the role of step-down, shunt, load, feedback, energy conversion and matching in low-frequency AC circuits, or plays the role of absorber and voltage divider in power supply circuits. It can also be used as shunt in oscillation circuits and attenuation adjustment and pulse forming circuits in transformers. It can provide very accurate and stable resistance value, handle high power load and have good thermal stability. Mainly used in precision instruments and measuring equipment, frequency converters and inverters, audio equipment, etc.
