Film capacitors are widely used as components in a variety of electrical circuits due to their robustness and high dielectric strength. The MKP386M422250JT8 is a high-precision multi-layer polypropylene film capacitor with self-healing properties. Its special construction and properties make it suitable for many standard and customized applications.

Applications

The MKP386M422250JT8 is mainly used for pulse and pulse capacitor storage circuits. It has a wide capacitance range, from 0.1 to 2200 μF, and an operating temperature range from - 55°C to +100°C. It is suitable for use in power electronic circuits, such as electric drives, inverters, and servo drives, as well as for other higher voltage applications, including motor drives, power supplies, and voltage regulators.

The capacitor is also suitable for double-sided audio frequency foil electrolytic capacitor applications, and its combination with high-performance AC and DC motors is an added advantage. The device\'s low ESR makes it ideal for high-quality audio applications.

Its high insulation resistance makes it suitable for long-term, interference-free operation in electronic equipment, as well as power electronic circuits where low frequency noise is generated, such as in medical equipment, telecommunication systems, and precision electronic equipment. The capacitor\'s high insulation resistance can also be used in outdoor power transformers.

Working Principle

The MKP386M422250JT8 works by storing electrostatic energy inside a dielectric material. This allows the electrons to travel with very little loss through the component, leading to very low voltage drift. This capacitor has a polypropylene film core that is surrounded by a thin layer of non-polarized electrolyte. The entire surface of the metalized film core is covered by a non-conductive coating. This construction makes it ideal for use in a variety of applications.

When a voltage is applied, the electrons on the surface of the metalized film core are forced to move in one direction. The static energy is then stored in the form of a “charge” in the film capacitance layer between the electrodes. As current flows between the electrodes, energy is stored in the dielectric material and stored in the capacitance layer, allowing low frequency and high voltage damping at the same time.

The MKP386M422250JT8 utilizes a series of special self-healing components. This helps to reduce the impacts of ESD, resonance and surge voltages, resulting in long-term use of the capacitor. This makes the capacitor particularly suitable in applications where long intervals between maintenance or replacement of the device are required.

Conclusion

The MKP386M422250JT8 is a high-precision multi-layer polypropylene film capacitor with self-healing properties. It has a wide capacitance range, from 0.1 to 2200 μF, and an operating temperature range from -55°C to +100°C. It is suitable for applications such as electronic drives, inverters, servo drives, AC motors, DC motors, telecommunication systems, medical equipment, power supplies, and voltage regulators.

The capacitor\'s self-healing properties protect it against ESD, resonance, and surge voltages, allowing for long-term, high-performance operation. This makes the MKP386M422250JT8 a robust and versatile choice for a wide variety of applications.
