Film Capacitors

A film capacitor is a type of capacitor that uses a dielectric film as a semiconductor substrate. It can be used in a variety of applications, including AC line filtering, high voltage DC blocking, high frequency coupling, decoupling and storage in signal conditioning circuits in amplifier and analog circuitry. It is also used in DC-DC converters, high speed switching and electronic switching applications.

MKT1813433065 Application Field and Working Principle

The MKT1813433065 film capacitor is a polyester film capacitor designed for use in AC line filtering applications. It is designed with an ultra-low profile, increasing the circuit board area available for use. The MKT1813433065 is rated for a voltage of 250VDC, a capacitance of 0.5÷3μF, and a frequency of 50Hz. It is used in combination with a film capacitor bank to form a large value capacitance suited for high frequency suppression and energy storage applications.The working principle of the MKT1813433065 film capacitor is based on the electrostatic field created between two metal plates separated by a dielectric material. The electrostatic field holds a charge that is proportional to the capacitor’s capacitance. The amount of charge stored depends on the capacitance of the capacitor and the applied voltage.When the applied voltage is high enough, the dielectric material in the capacitor will break down and create a large electric current. This current is then dissipated as heat, which can have destructive effects on the capacitor. To prevent this from happening, a voltage-limiting device, called a varistor, can be placed in series with the capacitor. The varistor allows current to flow but limits the voltage so that it does not exceed a predetermined level.In AC line filtering applications, the MKT1813433065 film capacitor is placed in series with inductor components in order to reduce the high-frequency AC noise. When the voltage across the capacitor is within its rated working voltage, a low-frequency AC current is allowed to flow while the high-frequency current is blocked and dissipated as heat.

Conclusion

The MKT1813433065 film capacitor is a versatile component. It can be used in AC line filtering, low voltage DC blocking, high frequency coupling, decoupling and storage of signal conditioning circuits, DC-DC converters, high speed switching, and other applications. It is designed with an ultra-low profile, making it suitable for a wide variety of uses. The working principle of the MKT1813433065 is based on an electrostatic field created between two metal plates, and its capacitance is determined by the amount of charge stored. It is best used with a film capacitor bank and a voltage-limiting device, such as a varistor, to prevent the dielectric material from breaking down and creating a destructive current.
