The residual voltage generated by the varistor cannot be removed because the varistor is a voltage-limiting component. Each type of varistor has a different residual voltage. The residual voltage increases with the current flowing through the varistor. The higher the residual pressure, the nonlinear component.What is the reason for defining the nominal voltage and residual voltage in the varistor?The nominal voltage is its protection voltage, that is, the varistor is turned on and off beyond the

In the process of manufacturing film capacitors, there are many factors affecting the performance of the product. Often, the control of the manufacturing process and the choice of process methods will play a decisive role in the change of the electrical properties of the capacitor. Therefore, when designing the capacitor, we are correctly selecting The dielectric field strength, internal and external structure of the product, main structural materials, capacitor heating and other factors must al

The application of ceramic capacitors has become more and more extensive, but we all know that ceramic capacitors will be damaged and will fail. There are many reasons for the failure of ceramic capacitors. This time we will divide the situation after the failure of ceramic capacitors. .Through the microscopic morphology of the ceramic dielectric found by scanning electron microscopy, it can be seen that the appearance of the failure is not only the color changes but also the existence of cracks
