Film capacitors are electronic components that use thin plastic films as a dielectric layer between two conductive metal plates. This type of capacitor is designed to support relatively large amounts of voltage without losing capacity or allowing significant electric leakage. The MKP383282140JFI2B0 capacitor is among the most popular film capacitors. Its application field and working principles are explained in the following sections.

Application Field

Film capacitors are mainly used in audio electronics. They improve the sound performance of audio systems by reducing distortion and eliminating noise from the system. The MKP383282140JFI2B0 is an example of a capacitor designed for use in audio electronics. It is a low-frequency capacitor with a maximum operating frequency of 120kHz at a rated voltage of 4kV. It is also capable of handling temperatures up to 105°C. In addition, the MKP383282140JFI2B0 is designed for applications where a constant voltage is needed, such as Car Audio and Hifi/Home Systems.

The MKP383282140JFI2B0 is also suitable for use in power supplies, where its smaller size and low resistance offers several advantages over other types of capacitors. It can be used in low-frequency switching power supply applications, and also in AC/DC power supplies. It is particularly useful for reducing in-rush current and improving the power factor in low-frequency power supplies.

Working Principle

The MKP383282140JFI2B0 film capacitor is designed to hold an electric charge in the form of an electric field. A dielectric layer of plastic is sandwiched between two metal plates, and the electric field is generated as an electric current passes through the capacitor. This electric field stores the charge. The MKP383282140JFI2B0 capacitor has a low dielectric loss and is therefore suitable for low-frequency applications.

When the MKP383282140JFI2B0 capacitor is used, the current will pass through the metal plates before reaching the dielectric material. The electric field created by the current creates an equal and opposite charge between the two plates. This charge creates an equivalent circuit between the two plates, which generates a unit of current. As the current passes through the capacitor, its charge decreases over time, resulting in a decrease in capacitance. This phenomenon is known as dielectric absorption.

The MKP383282140JFI2B0 capacitor is designed to provide excellent performance and reliability. Its high capacitance and low dielectric loss make it a reliable choice for audio electronics, power supply applications, and high-temperature applications.
