Film Capacitors

A film capacitor (or plastic film capacitor) is a type of capacitor that uses a thin plastic film as the dielectric layer. It is one of the most common types of capacitors used today, and is available in a wide variety of shapes, sizes, and construction styles. Film capacitors are used in a wide range of applications, from industrial electronics to consumer electronics.

The MKP385151125JC02G0 film capacitor is a metallized plastic film capacitor that consists of a polyester or polypropylene film as the dielectric layer, and thick metal electrodes that are sputtered onto the dielectric layer. This type of capacitor offers excellent performance, low losses, as well as excellent capacitance stability over a wide temperature range. Due to the properties of the dielectric, these capacitors are considered “low-ESR” (Equivalent Series Resistance).

Application Field

The MKP385151125JC02G0 film capacitor is typically used as a coupling device in audio filters, or as an AC line filter in consumer electronics. It can also be used as a DC blocking capacitor, and is often used as a snubber capacitor in inverters and motor drives. Additionally, film capacitors are commonly used in power supplies, switch mode power supplies, DC/DC converters, and radio frequency applications.

Working Principle

A film capacitor works on the same principle as other types of capacitors, which is to store a charge between two conducting plates. In the case of the MKP385151125JC02G0 film capacitor, the two plates are the metal electrodes that are sputtered onto the dielectric layer. The dielectric layer acts as an insulator between the two electrodes, allowing them to be charged without causing a short circuit. When a voltage is applied across the two electrodes in the capacitor, the dielectric layer stores the charge and generates an electrical field. The charge stored in the capacitor can be used to power electronic devices, or be released when needed to provide a voltage source.

Film capacitors are highly reliable and efficient, with excellent capacitance stability over long periods of time. Additionally, they are capable of handling high levels of voltage without deteriorating over time, making them a great choice for a variety of applications.
