Operating Principle

Firstly, when a DC voltage is applied across the capacitor terminals, electrical energy is stored within the dielectric material. Then, as the circuit load changes, the capacitor releases this stored energy gradually. Consequently, voltage ripple is minimized and sudden fluctuations are reduced. Therefore, Capacitor 6.8uF 400V ensures smoother power delivery and protects surrounding components from electrical stress. Furthermore, this controlled charge-discharge behavior improves overall circuit efficiency and reliability.
