Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a type of capacitor that uses a film of plastic film as the dielectric. The film can provide a very high capacitance, which makes them well suited for use in high-frequency and radio-frequency applications. They are also used in power supplies, high-voltage circuits, switching power supplies, and many other electrical applications. In this article, we will look at the application field and working principle of a 715P472916LA3 film capacitor.

Application Field

The 715P472916LA3 film capacitor is a high-stability type, providing a long-term stability of ±30ppm/OC. Its capacitance is typically 4700µF, with a rated voltage of 16V. The capacitor can be used in a wide range of applications, such as frequency adjustment, decoupling, noise reduction, and overvoltage protection. It is also suitable for use in switching power supplies, voltage regulators, telecom equipment, and any other applications where stability over time and temperature are important.

Working Principle

The 715P472916LA3 film capacitor is based on a polypropylene film dielectric. This type of film is very thin, yet extremely stable and provides a very high capacitance. The capacitor’s terminals are connected to a metalized layer, which is deposited onto the surface of the film. This allows the charges to be stored on both plates of the capacitor. The capacitor has a DC leakage current of less than 0.2µA, ensuring a reliable connection.

The 715P472916LA3 film capacitor operates by allowing a charge to build up between its two plates. As current flows through the capacitor, a voltage is developed across its terminals. This voltage is proportional to the amount of current, and this relationship can be represented by the equation V = IC, where V is the voltage, I is the current, and C is the capacitance of the capacitor.

In summary, the 715P472916LA3 film capacitor is a high-performance capacitor that is suitable for a variety of applications. Its high capacitance, long-term stability, and low leakage current make it an excellent choice for many different circuits.
