Film capacitors, also known as plastic film capacitors, are electrical components that are widely used in a variety of electronic circuits for different applications. Often featuring a high capacitance-to-size ratio, their main advantages include small physical size, excellent insulation properties and good stability. The QXP2K473KRP7FP is a type of film capacitor that is also known as an “Advanced Film Capacitor”.

In terms of design and construction, this type of film capacitor consists of a dielectric film, two metallic electrodes and two outer, protecting layers. The dielectric film is typically made of polyester or polypropylene while the outer layers are usually made from polyamide or a thermoplastic material.

The main application areas for this film capacitor include AC power line filtering, motor drive controls, signal processing, audio series filtering, DC power supply ripple suppression, and general AC applications. The specific working principle of this capacitor is based on the fact that it is able to store and discharge electrical energy when the voltage across it changes.

When the voltage across the capacitor is decreasing, charges of electricity are stored up on the electrodes. This creates an electric field between the electrodes which stores energy and produces a capacitance. As the voltage across the capacitor increases, the transfers of the charge current become faster and faster until the capacitance is completely discharged. This charging and discharging process is at the heart of the capacitor and is what allows it to be used in various applications.

The QXP2K473KRP7FP Advanced Film Capacitor can also boast higher temperature stability compared to other standard film capacitors. The operating temperature range of this capacitor is between –40 °C and +85 °C, when the temperature deviates, the capacitance or ESR of the capacitors will not change. Additionally, the QXP2K473KRP7FP has a lower ESR, higher ripple current capability and higher reliability than other standard film capacitors.

In terms of safety, this capacitor meets the ENEC (European Norms for Electrotechnical Components) requirements as well as UL, cUL, and TUV safety standards. It has also been tested according to IEC60384-14 and IEC60950 safety requirements which makes it suitable for use in a wide range of applications, including automotive, industrial as well as consumer electronics.

The QXP2K473KRP7FP advanced film capacitor is thus a robust, reliable and compact type of component which incorporates numerous benefits such as improved temperature stability and higher ripple current capability compared to standard film capacitors. As such, it is predominantly used for a variety of applications ranging from AC power line filtering to audio series filtering.
