The winding resistor is made of an insulating skeleton with a copper wire or a manganese copper wire.It has many advantages: high temperature resistance, high precision, high power.However, its frequency modulation is poor, mainly due to its large distribution inductance.A wide range of applications in low frequency accuracy.
The winding resistor is made of nickel-chromium or manganese copper wire, and the copper wire is made from the ceramic tube.The winding resistor is characterized by extremely high resistance. The noise is small in operation, stable and reliable, can withstand high temperature, still working properly at 170 ° C at ambient temperature.But it is large, the resistance is lower, mostly below 100kΩ.In addition, due to structural reasons, its distributed capacitance and inductance coefficient are relatively large, and cannot be used in high frequency circuits.Such resistors are typically used for buck or load in high power circuits.
