Film Capacitors

Film capacitors, otherwise known as plastic film capacitors, are passive electronic components that are used within a variety of electrical and electronic circuits. Film capacitors are nonpolar, non-tantalum, and non-ceramic, but instead consist of a thin, non-conductive polymer film that is sandwiched between two layers of conductive metal electrodes. When a voltage is applied to the electrodes, the electrostatic field created across the film produces an electrical capacitance.

PHE844RD6220KR06L2 application field and working principle

PHE844RD6220KR06L2 is a type of film capacitor which has the advantages of low ESR, excellent self-healing characteristic and low dielectric absorption. It can be used in a variety of electronic equipment, such as in flashlights, digital cameras, navigation devices, medical devices, ECUs, Bluetooth headsets, and other industrial/consumer goods. This particular type of capacitor is also suitable for noise filtering applications in communication system, LCD backlight control and switching regulator circuits.

Working principles of PHE844RD6220KR06L2 consists of the standard two main components, namely the two electrodes and the dielectric. When a voltage is applied to the electrodes, an electric field is created across the dielectric. This electric field causes the electrons to be attracted and repelled between the two surfaces of the dielectric. As a result, the electric field causes a displacement current to flow between the two electrodes.

Furthermore, the PHE844RD6220KR06L2 capacitor has a very low ESR and a high self-healing characteristic which make it a perfect choice for several applications. Its low ESR allows for a high frequency range, allowing for faster switching speeds or broadband switching applications. Its high self-healing characteristic also means that any damages caused to the film that disrupts the electric field do not result in permanent damages to the capacitor.

Its special features, such as low ESR, excellent self-healing characteristics, high yield strength and good dimensional stability, make this particular type of capacitor suitable for various industrial applications, such as capacitive overload protection, waveform shaping, and DC-DC voltage conversion. Furthermore, it can also be used in the automatic test equipment and process control systems.
