Film Capacitors

A film capacitor, also known as a dielectric film capacitor, is a capacitor that uses a film as the dielectric medium to store energy. These capacitors are among the most common and widely used on the market today, with their main advantage being their reliability and stability. This makes them suitable for use in a variety of applications, including audio, video and power systems.

MKP385468250JYI2T0 Application Field and Working Principle

The MKP385468250JYI2T0 film capacitor is a rectangular, epoxy-sealed capacitor. It has a metalized polyester film dielectric and is suitable for use in a variety of applications. It has an operating temperature range of -55°C to 85°C and a rated voltage of 250VAC. It is also resistant to moisture and other environmental conditions.

The working principle of the MKP385468250JYI2T0 film capacitor is the same as any other dielectric film capacitor. It consists of two metal plates, with the positive charge on one plate and the negative charge on the other plate. The dielectric material or film is sandwiched between the two plates, forming the capacitor. When an electric potential is applied, a space charge develops in the dielectric, creating a depletion layer. This affects the capacitance of the capacitor, leading to a change in the voltage across the plates.

The MKP385468250JYI2T0 film capacitor is highly suitable for a variety of applications, including audio and video circuits, signal processing circuits, and switching power supplies. Due to its high capacitance and low equivalent series resistance, it is also suitable for output filters and blocking filters in power supplies. Thanks to its high rated voltage, it can be used safely and reliably for high-voltage systems, meaning it is ideal for power factor correction, ignition systems, and other similar applications. Additionally, the MKP385468250JYI2T0 can also be used as a bypass capacitor, as it has a very low level of self-inductance, reducing the chances of frequency modulation and high-frequency interference.

The MKP385468250JYI2T0 is an excellent choice for engineers and technicians building reliable and stable systems, as it is able to withstand a wide range of temperatures and environmental conditions. Its high capacitance and low equivalent series resistance make it ideal for power factor correction and other similar applications, while its low self-inductance means it is suitable for use as a bypass capacitor. Thanks to its reliability and stability, the MKP385468250JYI2T0 is an excellent option for anyone looking for a reliable and stable dielectric film capacitor.
