Film Capacitors

Film capacitors, also known as plastic film capacitors or polymer film capacitors, are a type of capacitor distinguished by the use of a thin plastic film as the dielectric and electrodes on opposing sides of the film. These devices are used in electronic circuits to store charge, block or bypass AC current, and filter signals or radio frequencies. Every film capacitor contains a dielectric substrate that determines capacitance, insulation resistance, temperature performance, and velocity factor while resisting voltage breakdown. The dielectric can either be plastic or metal oxide, depending on required capacitance and dielectric strength. Plastic film capacitors offer higher capacitance than ceramic capacitors and make use of multiple layers of thin plastic film as the dielectric for higher voltage rating and higher performance-to-size ratios.

R60MI3470AA40J is a high-voltage type and has a capacitance of between 47 and 470 picofarads. The device is also specially designed to be relatively stable over temperature and show low dielectric absorption. It also has a high insulation resistance and features a long shelf life.

R60MI3470AA40J Application Field and Working Principle

R60MI3470AA40J film capacitors are used in a wide range of applications, including for voltage filtering and timing circuits in power supplies and motor drives, for data and signal processing, as well as in noise suppression, motor control, and DC-AC conversion applications. Commonly used in electronics, these capacitors can significantly reduce the voltage differences between two input circuits, thereby minimizing the risks associated with transient voltage due to voltage differences. This device is also used in many analog applications, where its high insulation resistance and stable capacitance contribute to its performance.

R60MI3470AA40J film capacitors are constructed from two plates of metal foil and a dielectric, or insulating material, placed between them. The metal plates carry electric charge which is stored as an electric field in the dielectric material between them. When a voltage is applied to the capacitor, charge is stored in the dielectric material, and the current is blocked. When the applied voltage is reversed, the capacitor will discharge by transferring the stored charge back to the circuit. In other words, a film capacitor acts like a closed circuit when voltage is applied, blocking current in one direction and allowing current to flow in the opposite direction.
