Film Capacitors

Film capacitors (including MKP385430040JC02R0) are usually used in power electronic applications to provide superior performance with low impedance and optimal power handling capability. They offer superior frequency and temperature characteristics, and are especially suitable for harmonic compensation as well as active filtering.

Applications

Film capacitors are used in applications such as power supplies, AC and DC filtering, snubbing networks, active notch filtering and damping networks, motor starting and running circuits, and for power factor correction.

Film capacitors can also be used for pulse energy storage, pulse shaping, surge protection, and also as a wide-ranging bypass capacitor. In general, they are more expensive than other type of capacitors, but offer distinct advantages in terms of frequency and temperature characteristics, as well as size and weight.

In addition, MKP385430040JC02R0 film capacitors are particularly suitable for applications that involve high input power and require superior frequency and temperature characteristics. They are also well suited for harmonic compensation and active filtering applications.

Working Principle

Film capacitors work on the principle of capacitance, which is the ability of certain materials to store electrical charge. These capacitors are constructed from multiple layers of dielectric materials that are insulated by a dielectric film. This works to create a combination of capacitance and insulation, allowing the capacitor to resist flowing current while storing electrical charge.

When a voltage is applied across the capacitor, the film becomes polarized, and electric field lines develop due to the electrical charge stored therein. This is known as dielectric polarization, and it determines the capacitor’s capacitance as well as its insulating properties. The stronger the electric field, the higher the capacitance and insulation levels.

The value of capacitance of the MKP385430040JC02R0 film capacitor can be altered by changing the thickness and dielectric permittivity of the film, as well as by adjusting the number of layers of the dielectric material.

Conclusion

MKP385430040JC02R0 film capacitors are widely used in power electronic applications due to their superior performance and low impedance. These capacitors offer superior frequency and temperature characteristics, and they are particularly suitable for harmonic compensation and active filtering. They work on the principle of dielectric polarization, and their value of capacitance can be altered by changing the thickness and dielectric permittivity of the film, as well as by adjusting the number of layers of dielectric material.
