Film capacitors, also known as plastic film capacitors, are capacitors that use plastic films as a dielectric material. The name film capacitor comes from the fact that the dielectric material of the capacitor is a thin plastic film, in which metal electrodes have been printed in the form of sheets, tracks or stripes by vacuum evaporation: different dielectric materials can be used, such as polystyrene, polypropylene, polycarbonate or polyester.

MKP383362100JFM2B0 Film Capacitor Application Fields

MKP383362100JFM2B0 Film Capacitors have a wide range of application fields in numerous electrical and electronic industries. They are widely used as smoothing and filtering capacitors in AC applications in countries with 220 and 115 Volt mains. As they are typically used in the power circuits, they are often designed to not cause any sound. MKP383362100JFM2B0 capacitors are also used in electromagnetic compatibility applications. They present superior electrical characteristics against interference in applications requiring high noise suppression, such as TV sets, audio systems, power supplies, LED lighting systems, etc.

Characteristics of MKP383362100JFM2B0 Film Capacitors

MKP383362100JFM2B0 Film Capacitors are available in various case sizes, from miniaturized axial and radial versions, to cables and snap-in cases measuring a few centimeters in length and width. Mostly they come as radial-leaded components, but some have polarised leads for grade and thermal class specific applications.

MKP383362100JFM2B0 Film Capacitors are known for having some of the best properties among other capacitors. They have a very low ESR (equivalent series resistance), making them ideal for most high-frequency applications, up to 1 MHz. Additionally, they have excellent stability over wide temperature ranges, often from -55 °C (−67 using special compounds) to 130°C, and long lifetime of up to 10,000 hours. On the downside, they often have a higher capacitance tolerance range than other types of capacitors, usually up to ±10%.

Working Principle of MKP383362100JFM2B0 Film Capacitors

A film capacitor consists of two metal plates, separated by a layer of insulating material, which forms the dielectric layer, and then further layers of plastic material to complete the form of the capacitor. This dielectric material is made of a strong plastic, such as polyester, and the metal plates are usually copper or aluminum. The capacitance of the capacitor is determined by the area of the plates, the distance between them and the type of dielectric material used.

When an alternating current, such as from a power supply, passes through the capacitor, it causes an electrical field which is concentrated between the metal plates. This field stores energy in the form of an electric charge and creates an opposing electric field to the current, called capacitance. This capacitance is what allows the capacitor to store and release energy, and it is proportional to the surface area of the metal plates and the type of dielectric material used.

In AC applications, the MKP383362100JFM2B0 Film Capacitor acts as a “smoothing” capacitor, which prevents sudden voltage “spikes” from appearing in the output of the circuit. It also works as an EMC filter, which can help reduce the amount of electrical interference from other components or sources.

Conclusion

The MKP383362100JFM2B0 Film Capacitor is an excellent choice for high current applications, and is suitable for those looking to reduce the amount of electrical interference in their circuits. They are relatively inexpensive, have good stability over temperature and have a long lifetime.
