Film Capacitors: MKP383316160JI02W0 Application Field and Working Principle

Film capacitors, also known as film dielectric capacitors, polypropylene capacitors, plastic film capacitors, or polymer film capacitors, are passive electronic components, which use dielectric film materials as their effective working dielectric layers and electrode layers.

The product name, MKP383316160JI02W0, indicates that it is a film capacitor type with a 4.7V voltage rating, with a tolerance of 10%. It belongs to the type of capacitors called Metallized Polypropylene Film (MPF) Capacitors.

Application Field

Film capacitors are widely used in various audio systems, DC filter networks, DC power supply circuits, and electronic switches.

They have the precise characteristics of low inductance, high insulation strength, excellent temperature stability, and high frequency performance. They have been developed with a compact structure and are often used in pulse circuits, wave filtering, signal coupling, etc..

Capacitors of this line are suitable for all types of high-voltage power supplies, such as electroplating power supplies, and household appliances, medical equipment, industrial and mining electrical equipment, telecommunications power supplies, and other fields especially those that require a high insulation strength and a wide temperature range.

Working Principle

The MKP383316160JI02W0 capacitor is a polypropylene film type capacitor with metallic electrolyte consisting of an extremely thin metalized polypropylene film as the dielectric layer, and aluminum foil as the electrode layer.

The working principle of this capacitor is simple yet reliable. An electric current passing through the capacitor applies electric energy to the dielectric layer, which is made of highly insulated polypropylene film. This energy creates a strong electric field within the dielectric material, which pushes the electrons in the metalized aluminum foil electrodes away from each other.

This separation of electrons forms a space charge between the electrodes, thus creating an electric potential difference across the capacitor. This potential difference creates an electric field that can store energy which can serve a variety of functions, depending on its application.

Due to its thin construction, the MKP383316160JI02W0 capacitor is able to operate remarkably well at high frequencies without detrimentally affecting their performance. In addition, they are stable over a temperature range of - 55°C to + 125°C.

This makes them suitable for use in high temperature applications, such as high-power electric circuits. Moreover, they have low dielectric losses, which allows them to maintain their capacitance for longer periods of time.

Due to their small size, light weight, high insulation strength, high frequency performance, and temperature stability, film capacitors have become an indispensable electronic component for various electronic devices and products.
