Film Capacitors

Film capacitors are used for storing electrical energy in electronics circuits and for signal filtering, coupling, and timing. They are composed of thin flexible films of electrically insulating material in a spiral, figure-8, or box-type arrangement, which gives them the appearance of a small cylinder or box. A charge is created when a voltage is applied across the films, which is then stored and released as small, controlled amounts of energy. Film capacitors have several advantages over other types of capacitors, including their low impedance, high temperature and voltage capabilities, wide frequency response, and low noise properties.

MKP1841318135 Application Field

The MKP1841318135 film capacitor is especially designed for AC motor start applications, such as home appliances, air conditioners, electric fans, elevators, etc. It is capable of operating at temperatures between -25 and +85 degrees Celsius and is resistant to extreme mechanical loads such as vibration and shock. Its temperature-stable capacitor element ensures long-term reliability and reproducible behaviour. The MKP1841318135 is designed with a highly efficient wax/epoxy coating for insulation purposes and offers superior protection, making it suitable for extreme environmental conditions.

Working Principle

The MKP1841318135 film capacitor consists of two metal layers separated by a thin film of insulating material. When a voltage is applied, electric charges collect on the two metal layers, creating an electric field. This electric field stores a certain amount of electrical energy, which is released as a current when the voltage is reduced or removed. Film capacitors also have high dielectric loss, making them ideal for voltage regulation, and superior noise filtering capabilities.

Conclusion

The MKP1841318135 film capacitor is ideal for applications that require a reliable source of power and good AC motor start performance. Its low impedance, high temperature and voltage capabilities, wide frequency response, and low noise properties make it an ideal choice for various industrial, automotive, and consumer electronics applications. It offers superior protection against mechanical loads such as vibration and shock and is designed with an efficient wax/epoxy coating for insulation purposes.
