Advantages and disadvantages of a wire wound resistor

图片
  Electricity has become an indispensable part of our daily life, and the use of electricity is more and more extensive, but the existence of electricity also has a certain degree of danger. The higher the current, the greater the danger, so the use of wire-wound resistors The role is highlighted. What is a  wire wound resistor : Wire-wound resistors are constructed by winding resistance wires on an insulating frame. The resistance wires are generally made of nickel-chromium and manganese-copper alloys with a little resistivity. The insulating frame is made of ceramic, plastic, metal coated with an insulating layer and other materials into a tube shape, a flat shape and other shapes. The resistance wire can be wound into one layer or multiple layers on the frame as required, or a non-inductive winding method can be used. This kind of resistance is divided into fixed and variable. It is characterized by strong working stability, good heat resistance, small error range, and the ...

Wire wound resistor

  Wire wound resistor  is a passive component, which is a kind of fixed resistor. Wire wound resistor is composed of a resistance wire wound on an insulating frame. Wire-wound resistors are made of nickel-chromium wire or manganese-copper wire and constantan wire wound on a porcelain tube. They are divided into fixed and adjustable types. Wire-wound resistors are characterized by high resistance accuracy, low noise during operation, reliable stability, can withstand higher temperatures, and can still work normally at an ambient temperature of 170 degrees Celsius. The role of winding resistance: Wire-wound resistance is composed of resistance wire wound on an insulating skeleton, and generally uses a medium with a certain resistivity, such as Made of nickel-chromium and manganese-copper alloys. Wire-wound resistors are mainly used to reduce voltage, shunt, load, feedback, transfer energy, and match in low-frequency AC circuits, or act as absorbers and voltage dividers in power ...
