Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components capable of storing electrical energy and subsequently releasing the charge. This type of capacitor is particularly valued for its information retention capabilities. They are mainly used for smoothing out voltage spikes, for instance in electrical motors, automation systems and power electronics. Aluminum electrolytic capacitors are defined by the voltage rating, capacitance and physical size, that all are needed to successfully operata a a device. E81D501VNN221MA35T is a type of product code which describe an specific Aluminum electrolytic capacitor under its own properties.

Application Field and Working Principle

Aluminum electrolytic capacitors are generally used for smoothing out voltage spikes, filtering out harmonics, and they carry out some forms of communications or power conditioning. In addition, it is of much interest to develop power electronics components with the same characteristics as the aluminium electrolytic capacitor without any drawbacks. The application of these capacitors is evident in power supplies, welding, and other power electronics. They are commonly used for power damping and voltage reduction.

The working principle of aluminium electrolytic capacitors is based on the double-layer effect. When a voltage is applied from the outside to the interior of the capacitor, provoked by the electrodes or contact of the electrolyte, an electrical current is induced to flow within the aluminium electrolytic capacitor. Subsequently, the voltage creates an electric field between the electrolyte and the metal plates. This electric field causes electrons to move towards the positive plate. This motion of electrons creating a negative charge on the electrolyte as well as a positive charge on the metal plates.

This “induced” charge is the one that creates the capacitor effect, meaning that the energy is stored in the electric field between the metal plates and the electrolyte. When this field is charged, the capacitor is said to be “charged”, and when the energy in the electric field is depleted, it is said to be “discharged”. This process is reversible, meaning that charge can be stored and retrieved several times.

The capacitor acts as an electrical circuit component, meaning that it functions as a link between different electronic components. It is capable of storing and then releasing electrical energy in order to ensure that the different hardware components linked to it have enough current to function properly. Following this, the capacitor can be recharged and these digital components can keep functioning.

To sum up, E81D501VNN221MA35T is an aluminum electrolytic capacitor which is able to store and release electrical energy. It is mainly used to smoothen out voltage spikes and filter out harmonics, so that power supply and power conditioning work accurately. It is a component with a high value, since it assures information retention capabilities.
