Working Principle

The ECQ-E2825KFW is a polypropylene film capacitor. Polypropylene is a plastic material with high dielectric strength and excellent electrical insulation properties. The capacitor consists of two metal electrodes separated by a dielectric. An electrical charge is stored in the capacitor between the two electrodes. When a voltage is applied to the electrodes, a current flows through the capacitor and the amount of charge in the capacitor is changed. This change in charge is called the capacitance.

The performance of the capacitor is determined by a few important parameters, such as its capacitance, equivalent series resistance (ESR), and voltage rating. The capacitance is a measure of how much charge is stored in the capacitor, while the ESR determines how quickly the capacitor can respond to changes in voltage. The voltage rating determines the maximum voltage that can be applied to the capacitor without damaging it. The ECQ-E2825KFW is designed to operate in a wide range of applications, and it offers reliable operation in high-temperature, high vibration, and high-frequency environments.
