Film capacitors may have a variety of characteristics, such as low loss, high stability over temperature, self-healing and the ability to operate over a wide temperature and voltage range. They are also highly resistant to moisture and shock, making them ideal for a range of applications, from power line filtering to metering and measurement, to high frequency switching.

The MKP1848630454P4 is a high performance Film Capacitor with a wide application field. It offers a rated capacitance of 18µF with 10% tolerance, a voltage rating of 630VAC and a temperature range of -40° to 105°C. The MKP1848630454P4 is equipped with a self-healing metallized polypropylene dielectric that is designed for a long service life and reliable performance.

The working principle of the MKP1848630454P4 is based on the well-known capacitor regulation principles. A capacitor is an electrical component utilized to store energy in the form of an electrical field. A capacitor consists of two conducting plates separated by an insulating material (generally paper, plastic or ceramic). When a voltage source is connected across the two conducting plates, an electric field forms between the plates, causing an accumulation of electrons on one of the plates. This electrical field or charge can then be used to store energy.

The MKP1848630454P4 contains two dielectric materials. The first is polypropylene, which is a plastic material that is used as an insulator between the two conducting plates. The second dielectric material, the metallized polypropylene, is a metal layer deposited on the plastic film. This metal layer acts as an extra protection layer to increase the durability and reliability of the overall capacitor.

The working principle of the MKP1848630454P4 is based on the generation of an electric field between the two capacitance plates. This electric field generates a charge which is then stored in the capacitor. When the circuit is closed, electric current flows through the plates, discharging the capacitor and restoring the electric field. The process then continues to repeat itself in a cyclical manner.

The MKP1848630454P4 Film Capacitor is ideal for a wide range of applications including power line filtering, high frequency switching, power supply filtering, and energy storage and switch mode power supply applications. Due to its self-healing metallized polypropylene dielectric, it has superior mechanical durability and reliable performance, making it suitable for extended service life under rigorous operating conditions.
