Inductive Non-Inductive Cylindrical Fixed Wirewound Resistor KNP 0.5W 1W 2W 3W 5W
Function Of The Fixed Wirewound Resistor KNP 0.5W 1W 2W 3W 5W
Wire-wound resistors are composed of resistance wires wound on an insulating frame, and are generally made of a medium with a certain resistivity, such as nickel-chromium, manganese-copper and other alloys. Wire-wound resistors are mainly used to perform the functions of step-down, shunt, load, feedback, energy transfer, matching, etc. in low-frequency AC circuits, or act as absorbers and voltage dividers in power circuits, and can also be used as oscillations Attenuation adjustment in loops and transformers and shunts in pulse forming circuits. In addition, it can also be used for discharge and spark suppression of filter stage capacitors in rectifiers. At the same time, it can be widely used in household appliances, medical equipment, automobile industry, railway, aviation, military equipment and other fields.
