Film Capacitor Features and Optimization Suggestions

Views:1     Author:Site Editor     Publish Time: 2019-01-16      Origin:Site

Capacitance is an important electronic component in the circuit. Therefore, we must pay attention to protect it when using it, and extend its service life as much as possible. At the same time, the film capacitor is an important capacitor in the capacitor. It is an electron. One of the electronic components used in the equipment is widely used in the circuit of direct communication, coupling, bypass, filtering, tuning loop, control and so on. Therefore, we need to optimize the film capacitor to extend its life.


Film capacitors generally do not suffer from short-circuit failure, but they suffer from capacity stability problems because of the gradual reduction in capacity under long-term operation, so we need to reduce their long-term operation and high load. Run, and control its working temperature. If the temperature is too high, the capacity loss will be more serious. At the same time, the film capacitor can be replaced with a metal foil capacitor. The metal foil capacitor can reduce the loss of capacity.


The film capacitor is not very good for high current. We can change the traditional single-sided metallized film to make the electrode and use the double-sided metallized film as the electrode, and enhance the thickness of the metallization layer. Improve the welding process, which can increase its ability to withstand large currents. The film capacitor is sealed with a plastic case to control the dimensional consistency, has excellent flame retardant performance, and has good self-healing there. The reliability is very high. The metal film capacitor has been widely used in filtering, noise reduction and low. In the pulse circuit.
