Working Principle

The KMQ250VS471M25X30T2 is an aluminum electrolytic capacitor which uses an electrolyte to store electric charge. It uses a chemically reactive electrolyte that reacts with the aluminum-oxide layer on the aluminum electrodes to form a dielectric layer allowing electric charge to be stored. As electricity is supplied to the device, the electrical charge builds up on the terminals causing the dielectric to thin as the electrolyte shrinks. When the charge reaches a certain level, the voltage across the terminals will cause the dielectric to burst and it will become electrically conductive and the capacitor will function. The capacitor can also absorb energy from a power supply. This occurs when the device absorbs the electrical current of the power supply and stores it, similar to the way the capacitor charges up during its use. The capacitor will then release the stored energy back into the power supply as needed, allowing for a more efficient conversion of the energy. The KMQ250VS471M25X30T2 aluminum electrolytic capacitor is designed to provide reliable power and performance in a variety of applications. It is easy to install and its high operating temperature allows it to be used in a wide range of conditions. With its high performance, energy storage, and long life, this capacitor is a great choice for many applications.
