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.
