Working Principle

The 199D18X9016D2V1 capacitor operates using the principle of electrical capacitance. A capacitor is a two-terminal electronic component composed of two metal plates separated by an insulating material known as a dielectric, such as air or ceramic. When a voltage is applied across the capacitor plates, an electric field forms between them. This electric field attracts opposite charges between the two plates, resulting in a voltage drop across the capacitor and the flow of current. The capacitor is able to store the energy and then release it when the voltage is removed. The amount of charge stored depends on a number of factors, including the type of dielectric and the amount of capacitance. In the case of the 199D18X9016D2V1 capacitor, the capacitance is 18µF.
