Winding resistance

Introduction to product description: Wire-wound resistors are made of constantan wire or manganin wire wound on an insulating frame. It has the advantages of high temperature resistance, high precision and high power. But its frequency modulation characteristics are poor, which is mainly due to its large distributed inductance. It is widely used in low-frequency precision instruments. Winding resistors are made of nickel-chromium wire, manganese copper wire, and constantan wire wound on a porcelain tube. Divided into fixed and adjustable. The winding resistance has the characteristics of high resistance accuracy, low noise, stable and reliable operation, etc. High temperature resistance, can work normally at 170℃. But it is large in size and low in resistance, mostly below 100kΩ. In addition, due to structural reasons, its distributed capacitance and inductance are relatively large and cannot be used in high-frequency circuits. This kind of resistance is usually used in high-power circuits to reduce voltage or load.

Product Usage:

Wire-wound resistors are composed of resistance wires wound on an insulating frame, generally made of a medium with a certain resistivity, such as nickel-chromium, manganese copper and other alloys. Wire-wound resistors are mainly used for functions such as step-down, shunting, load, feedback, energy conversion, and matching in low-frequency AC circuits, and can also be used as absorbers and voltage dividers in power circuits. It can also be used as a shunt for oscillating circuit, transformer attenuation adjustment and pulse forming circuit. In addition, it can also be used for the discharge and spark suppression of rectifier bridge filter stage capacitors. At the same time, it can be widely used in household appliances, medical equipment, automobile industry, railway, aviation, military equipment and other fields.
