Film capacitors’ features and optimization suggestions

Capacitors are important electronic components in a circuit. Pay attention to protection when using. Make it as long as possible. At the same time, film capacitors are important capacitors and are one of the electronic components used extensively in electronic equipment. It is widely used in circuits, such as DC block and AC pass, Coupling, bypass, filtering, tuning loop, control, etc.

Film capacitors have problems with capacity stability, but generally don’t have short circuit failure, because film capacitors gradually decrease in capacity during long periods of work. Therefore, it is necessary to reduce the long-term operation and high-load operation of film capacitors and control the operating temperature. The temperature is too high, the capacity loss is more serious. Alternatively, replace film capacitors with metal foil capacitors, which can reduce the loss of capacity.

Film capacitors aren’t capable of withstanding large currents. The single-sided metallized film was changed to a double-sided metallized film as an electrode. At the same time, increase the thickness of the metallization, improve welding process. The plastic case is sealed and packaged with good dimensional consistency. Excellent flame retardancy, good self-healing, very high reliability. Therefore, film capacitors are widely used in filtering, noise reduction and low-pulse circuits.
