Introduction to Film Capacitors

Capacitors are devices that store electrical energy. Film capacitors (also known as plastic film capacitors, film dielectric capacitors or film caps) are electrical components that use a thin film of plastic to provide a dielectric medium between its two conductors. Most film capacitors are used for general-purpose applications such as power supply filtering, signal coupling, and energy storage.

Application Field and Working Principle of MKP383316100JFP2B0

The MKP383316100JFP2B0 is a 400v mica film capacitor available from manufacturer MKP. It has a low dissipation factor and is suitable for a variety of applications such as motor start, lighting, and energy storage. It is rated up to 100kHz and rated for 12.5A.

The working principle of this capacitor is the same as other film capacitors. The capacitor is constructed with two electrodes or plates which are separated by an insulating dielectric material - in this case, mica. When an electric voltage is applied across the two electrodes, an electric field is formed across the dielectric and charge is stored. The polarization process produces a dielectric insulation between the two electrodes, resulting in an increase in capacitance and thus, the ability to store more charge.

The MKP383316100JFP2B0 capacitor has double capacitance stability when compared to other capacitors due to the mica material used as dielectric. The capacitance of this capacitor remains constant at temperatures from –55℃ to 100℃, which makes it ideal for motor start applications. In addition, its humidity proof design and low dissipation factor of 55 percent ensure temperature stability and a longer lifetime.

Benefits of Film Capacitors

Film capacitors provide superior performance and reliability compared to other types of capacitors. They offer a wide range of benefits, including:

• High capacitance density
• Low dielectric absorption
• Low inductive and resistive losses
• High insulation resistance
• Excellent stability over temperature and humidity
• High current handling capacity
• Excellent electrical noise rejection
• Good tolerance to environmental stress
• Long life expectancy

These characteristics make film capacitors well-suited for a variety of applications, such as power supplies, connecting inductors and motors in power tool applications, and even high-frequency power supplies.

Conclusion

Film capacitors are widely used in many applications due to their performance and reliability. The MKP383316100JFP2B0 capacitor specifically offers superior temperature stability, humidity proof design, and low dissipation factor, making it suitable for motor start and energy storage applications. Additionally, film capacitors offer a wide range of benefits, such as high capacitance density, good tolerance to environmental stress, and long life expectancy.
