Film Capacitors

Capacitors are electronic components used to store and release electrical energy. Among these capacitors, film capacitors are the most frequently used in comparison with others. Distinguished from those bulky and large ceramic capacitors, film capacitors are small and lightweight, offering a wide variety of sizes and resance values. Among these variants, MKP385615040JPP4T0 is a common model used in many occasions. It is a marked capacitor, branded by Vishay-BC Components, a reliable and trustworthy capacitor manufacturer.

MKP385615040JPP4T0 Application Field

As its name implies, this model of film capacitor is mainly employed in applications that involve higher resonance, such as communication applications, voltage stabilizers, electric motor drives, electronic ballasts and high frequency rectifiers. As this capacitor contains multiple-layer metalized polypropylene material it can withstand temperatures as high as +105°C.

MKP385615040JPP4T0 Working Principle

The MKP385615040JPP4T0 model of film capacitor consists of multiple layers of etched foil and plastic films. This layered structure forms a series of round plates separated by insulating polymer. The combination of the plastic film and insulating polymer provides not only high capacitance, but also high voltage and frequency ratings. This capacitor has a voltage rating of 400 Vac, and a selected resonance frequency of 3660Hz- 4500Hz. The capacitor is polarized, meaning that one terminal of the capacitor will be designated positive, and the other negative.

When an electric charge is impressed on the capacitor, the positive terminal will repel the positive charge of the electric field, while attracting the negative charge, and vice versa. This phenomenon forms electric dipoles at the terminals of the capacitor. As the charge on the capacitor continues to build, a certain point is reached where the capacitor\'s capacitance is maximized and an electric field is created, producing a virtual storage tank for electric energy.

When the electric charge is released, the electric dipoles will be rearranged and the electric energy stored in the capacitor will be dissipated, producing electric current. This is the basis of the MKP385615040JPP4T0 model film capacitor’s operation.

Conclusion

The MKP385615040JPP4T0 model of film capacitor is an ideal choice for applications that require higher resonance. This model of capacitor offers a wide range of frequency and voltage ratings, making it a perfect choice for a variety of applications. Most of all, the multiple layers of plastic films and the unique layered structure provide great protection for the capacitor and reduce the risk of electrical failure.
