Film Capacitors

Film capacitors, also known as plastic film capacitors, are two-terminal devices composed of a thin plastic film as a dielectric, and are used in a variety of applications. They are constructed by winding a conducting metal foil around an insulating plastic film, which is then encapsulated in epoxy for protection. The ability of film capacitors to reliably store and release electrical energy makes them a popular choice for signal processing in high frequency and high power applications.

The MKT1818368256G is a type of film capacitor specifically designed for use in high frequency applications. It is designed with a non-polarized structure, allowing it to be used in both AC and DC circuits. The device features an operating temperature range of -55C to +125C and is rated for a maximum voltage of 16V.

The working principle of a film capacitor is based on the effects of dielectric absorption and polarization. It begins with the application of an electrical field to the dielectric material. The dielectric material is a combination of two single layers of plastic films with conducting metal foils that are sandwiched between them. When the electrical field is applied, the molecules of the dielectric material move and attempt to align themselves with the electric field. This alignment of the molecules constitutes a polarization that creates a capacitance, which is measured in Farads. The capacitance value of the film capacitor is proportional to its surface area and the dielectric constant of the material.

When it comes to the application of the MKT1818368256G film capacitor, it is best suited for applications that require highly reliable and consistent performance in harsh environments. It is ideal for use in power supplies, resonant circuits, amplifiers, LCD TVs, and automotive audio systems. Additionally, it can be used in high frequency switching circuits, DC-DC converters, LED lighting, and signal lines.

Given the MKT1818368256G\'s wide range of applications, it is no surprise that it has become one of the most reliable and popular film capacitors available. Its non-polarized construction and versatile operating temperature range make it an ideal choice for use in high-frequency and high-power applications. Furthermore, its high capacitance value makes it capable of handling a wide range of critical signals. With its reliable performance and reasonable cost, the MKT1818368256G is sure to remain a preferred choice for many applications.
