Film capacitors, also known as plastic film capacitors, are a type of capacitor consisting of a plastic film as the dielectric. The capacitor is also equipped with metal electrodes for contact with the dielectric, which are connected to the capacitor\'s terminals. Compared to other capacitors, like ceramic and electrolytic types, film capacitors offer a variety of advantages including higher capacitance, excellent stability, and a much longer lifespan.

MKT1822410255G is one of the film capacitors that has gathered a lot of attention since its introduction. This model is manufactured by using the metallized polypropylene film, which offers it multiple advantages like low dielectric absorption, high insulation resistance, low voltage coefficient, higher heat resistance and low ESR. The use of this type of film also makes MKT1822410255G more tolerant to temperature and humidity than commonly used electrolytic capacitors.

Application Field

MKT1822410255G is widely used in many fields, most notably in high current and high voltage power circuits. When compared to ceramic capacitors, their high capacitance and low ESR make them ideal for use in power Electronics applications, including power supplies, AC/DC converters, switching regulators for LED drivers, piezoelectric applications, and more. In addition, MKT1822410255G can be used in high-end audio systems, medical applications, and frequency characteristics applications.

Working Principle

The working principle of MKT1822410255G is based on the concept of dielectric polarization. When a voltage is applied to the capacitor, electric dipoles are induced in the dielectric material, resulting in an increased capacitance. The amount of charge stored in the dielectric is linearly proportional to the applied voltage and inversely proportional to the frequency of use. The charge stored in the capacitor is represented by C, which is equal to the capacitance value multiplied by the applied voltage.

In addition, due to the dielectric material’s high insulation resistance, MKT1822410255G are able to handle very high voltages, making them suitable for operation even under a wide range of temperatures. This makes it well-suited for applications that require reliable performance in extreme conditions.

Compared to alternative capacitors like electrolytic and ceramic types, film capacitors like MKT1822410255G are not only smaller but also offer other advantages, such as higher capacitance, excellent stability, and a much longer lifespan. Although they are slightly more expensive per unit, their cost-effectiveness is still quite attractive for many applications.
