Film capacitors are widely used in many electrical applications due to their low ESR (equivalent series resistance), low dissipation factor, low leakage, high stability, high insulation resistance and high temperature and repetitive temperature cycle ratings. These advantages are a result of the unique properties of the dielectric film that makes it the preferred choice for critical applications like power conversion, medical electronics, automotive and industrial applications. Let\'s take KP1830215011D as example to learn its application field and working principle.

Application Field

KP1830215011D film capacitors are designed and manufactured as power capacitors for high frequency switching power supplies and DC/DC converters. They are suitable for power supply sizes up to 10kV and are frequently used in solar inverters, electric buses and other applications requiring high insulation resistance and high current handling capability.

KP1830215011D film capacitors meet UL, EMI, IEC standards and have excellent welding properties to provide a more robust and reliable connection. Moreover, the capacitors can be factory assembled and are excellent for automation, reducing the labor cost and maintaining high quality in assembly processes.

Working Principle

The working principle of film capacitors is based on the fact that a thin film of dielectric material is placed between two conducting plates, which are charged with electrical current. The electric field that is generated causes an electric charge to be stored on the plates. This charge is inversely proportional to the dielectric constant of the film material.

Since the dielectric material used to build film capacitors has an extremely high electrical breakdown strength, the actual electric field created is much stronger than that of other types of capacitors. The result is a much higher capacitance per unit volume compared to other types of capacitors.

Film capacitors are very efficient at blocking high frequency noises from interfering with the signal. The reason for this is because of the dielectric material’s high breakdown strength, which effectively blocks high frequency interference. This makes film capacitors ideal for use in high frequency applications, such as radio, television, and high speed computing applications.

In addition, the dielectric material used to make film capacitors also has high temperature and repetitive temperature cycle ratings, making them highly reliable for applications which require long-term operation.

KP1830215011D film capacitors use a metallized construction to minimize volumetric size with the same capacitance value. The metallized construction also provides greater stability and reliability over the lifetime of the capacitor.

Due to their excellent physical and electrical characteristics, KP1830215011D film capacitors are suitable for a wide variety of applications in different fields. They provide a reliable power solution for high frequency switching power supplies and can be used in industrial and medical applications. These capacitors can also be used in automotive applications, as they have excellent temperature and repetitive temperature cycle ratings.
