Film capacitors, also known as plastic or polymer film capacitors, are a type of capacitor made from a thin film of plastic and an anti-corrosion coating. Most film capacitors are polarised because the electrolyte in the film determines the capacitor’s capacitance. MKP385330250JKI2B0 is a combination film capacitor is designed for AC power line applications and for extended long-term exposure to severe environmental conditions. In this article, we will discuss its application field and working principle.

Application Field

MKP385330250JKI2B0 is a combination film capacitor which offers a combination of features such as high capacitance, high voltage rating, and low ESR in a package with a very low profile and small volume. It can be used in electric power applications and in medical equipment, such as imaging systems or ultrasound machines. The combination of high capacitance, high voltage rating, and low ESR makes it a suitable choice for use in applications such as high frequency inverters, DC-link filters, motor and power control systems, remote control systems, and switching power supplies.

Working Principle

The working principle of MKP385330250JKI2B0 is based on the fact that it consists of a thin plastic film with an anti-corrosion coating. The electrical properties of a film capacitor are based on two conducting layers separated by a dielectric film. When a voltage is applied to a film capacitor, electrical charges accumulate on the dielectric film, increasing the capacitance of the device. The amount of charge accumulation depends on the thickness, quality and conductivity of the dielectric film. The higher the dielectric constant and the lower the resistivity of the material, the higher the capacitance will be.

The main advantage of using a film capacitor is that they can operate with a very low ESR (equivalent series resistance), allowing them to operate at higher frequencies and achieve better performance. This makes them ideal for applications that require high-frequency switching, such as power converters and inverters. As mentioned earlier, they also offer a high capacitance, allowing for a high-voltage application. Another benefit is that they are very stable over time and temperature, making them suitable for applications that require a high degree of reliability.

The MKP385330250JKI2B0 combination film capacitor is designed with a combination of features to meet the specific requirements of AC power line applications and for extended long-term exposure to severe environmental conditions. In order to ensure the highest technical performance and reliability, the capacitor is provided with a patented high temperature tolerance with an operating temperature range from -40°C to +85°C. This ensures a long lifespan and reliable operation even in harsh environments.

In conclusion, the MKP385330250JKI2B0 combination film capacitor is designed for AC power line applications and for extended long-term exposure to severe environmental conditions. Its combination of features such as high capacitance, high voltage rating, and low ESR make it a good choice for a range of high-frequency switching applications. It is highly reliable and stable over time and temperature, making it ideal for applications that require a high degree of reliability.
