Film Capacitors

Film capacitors, also known as plastic film capacitors, polyester capacitors, metalized film capacitors, and AC motor capacitors, are electrical components used in electronic circuits and engineering applications. Film capacitors are primarily built with a polarizable dielectric, also known as a thin film, formed between two or more electrically conductive surfaces. Among many other uses, they are used in a variety of AC applications such as audio and video amplifiers, power supplies, high voltage DC/DC converters, and AC motors.

The MKT1813422256 is a type of film capacitor that is commonly used in AC applications. This type of capacitor is composed of a metallic film with a polyethylene terephthalate (PET) film as the dielectric. The PET film is then wound around a cylindrical bobbin in a convoluted winding pattern. This provides the MKT1813422256 with low leakage and excellent insulation capabilities.

The working principle of the MKT1813422256 film capacitor is based on two simple concepts: capacitance and voltage. Capacitance is the amount of electrical energy that a capacitor can store, measured in Farads. Voltages create differences in electric potential, and these differences cause electric charges to accumulate and store within the capacitor. The capacitance of a capacitor is determined by the area of the electrodes, as well as the distance between them and the dielectric material that separates them.

The primary application of the MKT1813422256 film capacitor is in AC motor applications such as transformers, transistors, and amplifiers. It is beneficial in these applications due to its high voltage rating and low DC leakage current. This class of film capacitor is also commonly used in high voltage DC/DC converters, providing better control compared to electrolytic capacitors due to thinner dielectric films, higher energy storage capabilities, and resistance to high temperatures.

In addition, the MKT1813422256 film capacitor is capable of providing excellent noise filtering and efficiency when used in audio and video amplifiers and power supplies. It can also be used in resonant circuits and resonant power supplies, where high frequency AC circuits require high frequency capacitors. Finally, it is also ideal for applications that require excellent temperature stability, such as temperature compensation networks and EMI filter circuits.

In conclusion, the MKT1813422256 film capacitor is a versatile and reliable component that is ideal for a variety of AC motor applications, as well as high voltage DC/DC converters, audio and video amplifiers, power supplies, resonant circuits, and temperature compensation networks. It provides high voltage capability, low DC leakage current, excellent noise filtering, and excellent temperature stability, making it an ideal choice for a variety of industrial and commercial applications.
