Additionally, it is able to handle temperatures from -55°C to +105°C and has excellent temperature stability, making it an ideal choice for industrial use. Its wide capacitance range, high voltage ratings, and low ESR make the 125PPA202KS Film Capacitor especially suitable for high frequency purposes, such as in switch mode power supplies.

Working Principle

The 125PPA202KS Film Capacitor is made up of two metal electrodes that are separated by a thin film of dielectric material. The dielectric material acts as an insulator, so that a potential difference can be created between the two electrodes. This potential difference creates an electric field within the capacitor, causing an electric charge to be stored between the two metal plates. As the voltage across the capacitor varies, the electric field strength also changes, resulting in a change in the amount of charge stored.

In operation, the capacitor can be used to provide either voltage or current. When the capacitor is used to store voltage, it is referred to as a “charge storage” device, as it stores the charge as the voltage across the plates varies. When the capacitor is used to provide current, it is referred to as a “current source”. In this case, the stored charge is used to provide a current through the capacitor.

The 125PPA202KS Film Capacitor is an incredibly useful and versatile component that can be used in many different applications. Its broad range of capacitance values, temperature and voltage ratings make it suitable for use in a variety of different circuits and industrial applications.
