Introduction of Film Capacitors

Film capacitors, also known as plastic film capacitors, are electrostatic capacitors that use a polymer film as the dielectric. Film capacitors are widely used in a variety of electronic applications due to their low cost, low ESR, high capacitance, and stability over a wide temperature range of -55 to 125 degrees Celsius. There are many types of film capacitors available, including polyester film capacitors, polycarbonate film capacitors, and polypropylene film capacitors.

Application Field and Working Principle of MKP385291085JC02R0

The MKP385291085JC02R0 is a polyester film capacitor manufactured by Vishay. It is designed for AC and pulse applications in the range of 50 V to 500 V. This capacitor is typically used in inverters, drive circuits, and power supplies. The working principle of the MKP385291085JC02R0 is relatively simple. When AC or DC voltage is applied to the capacitor, an electric field is created between the capacitor plates and the dielectric. This electric field produces a dielectric polarization which causes the dielectric to become an electrical insulator, allowing charge carriers to accumulate on its surface. The accumulation of charge carriers on the dielectric produces a potential difference which results in a capacitance between the plates. The MKP385291085JC02R0 capacitor exhibits superior performance thanks to its low ESR (equivalent series resistance). The capacitor also features excellent AC ripple rejection, making it suitable for RF applications. It has a wide temperature range and is resistant to vibration, making it an ideal choice for harsh environmental conditions such as wind turbines or automotive applications.

Conclusion

In conclusion, the MKP385291085JC02R0 is a polyester film capacitor designed for AC and pulse applications. It features low ESR, high capacitance, and excellent AC ripple rejection. It is suitable for use in extreme environments due to its wide temperature range and resistance to vibration. The working principle of the capacitor is relatively simple, as electric fields are created between the capacitor plates and the dielectric, resulting in a capacitance between the plates.
