Film Capacitors: MKT1818268406D Application Field And Working Principle

Film capacitors, also known as a plastic film capacitor, are commonly used in many circuits, from large power supplies to small hearing aids. The MKT1818268406D is a common type of film capacitor, and it is known for its reliability and high capacitance for its relatively small size. In this article, we will explore the application field and working principle of the MKT1818268406D.

Application Field

The MKT1818268406D is especially suitable for applications where electrical insulation, high stability and long-term reliability are required. It is commonly used in inflection power supplies, variable frequency drives (VFDs), consumer electronics, clock circuits, telecommunications, and industrial computers.The MKT1818268406D has a wide operating temperature range from -55℃ to +125℃, and a low dissipation factor for exceptional performance compared to similar capacitors. The MKT1818268406D also has a high capacitance for its relatively small size, making it a great option for many applications.

Working Principle

The film capacitor, such as the MKT1818268406D, is made from two metal electrodes which are separated by a thin insulator film. The thin insulator film can be made from either polyethylene, polypropylene, polystyrene, or any other synthetic material, depending upon the application.When an AC voltage is applied to the capacitor, an alternating electric field is created and this causes electrons to flow across the insulated film. This creates an electric charge which is stored in the capacitor until the voltage is removed. The amount of charge stored in the capacitor is determined by its capacitance, which is directly related to the thickness of the insulating film used.

Conclusion

The MKT1818268406D is a highly reliable and efficient film capacitor that is suitable for many applications. It is designed for a wide operating temperature range, high stability, and long-term reliability, making it a great choice for power supplies, computing, telecommunications, and other applications. The working principle of the MKT1818268406D is based on the use of two metal electrodes separated by an insulating film, and the capacitance of the capacitor is determined by the thickness of the insulating film used.
