Operating Principle

Firstly, when voltage is applied, the capacitor stores electrical energy within its dielectric material. Then, as the circuit demands energy, the capacitor releases this charge in a controlled manner. Consequently, voltage ripple is reduced and sudden voltage variations are absorbed. Therefore, Capacitor 15uF 400V ensures smoother operation and protects connected components. Furthermore, this controlled charge-discharge process improves the reliability and lifespan of the entire electronic system.
