Film Capacitors

The MKT1817318015 is a type of film capacitor that is used for a variety of applications. Film capacitors are made from thin sheets of polyester film and have a good dielectric strength, high stability, and low loss. They also have good self-healing and high ripple current capabilities.

Applications

Film capacitors are commonly used in AC power supplies, DC-DC converters, microprocessor circuits, and motor controls. They are also used in applications where large TD piezoelectric effects, low ESR and ESL, high surge current stability, and high voltage performance are required. Film capacitors are also well suited for high precision current sensing, SNR improvements, and radio frequency applications.

Working principle

Film capacitors operate on the principle ofDielectric Absorption. This is the process by which a capacitor absorbs energy from an electrical potential, which is converted into an electric field on one side of the dielectric. When the electric field is removed, the energy is then released. This allows the capacitor to store and release energy rapidly, which is necessary for high frequency applications.

Film capacitors are also known as plastic dielectrics because they are made from a thin sheet of polyester plastic. This dielectric properties are not affected by temperature and humidity, giving them good long-term stability. Additionally, they are electrically stable and resistant to breakdown in high voltages, making them ideal for applications involving high power.

Conclusion

The MKT1817318015 Film Capacitor is a versatile component that can be used for a wide range of applications. It has a good dielectric strength, high stability, and low loss, as well as good self-healing and high ripple current capabilities. Film capacitors are also well suited for high precision current sensing, SNR improvements, and radio frequency applications.
