Aluminum Electrolytic Capacitors

The 100YXG470MEFCGC16x25 is an aluminum electrolytic capacitor, a type of capacitor used to store electrical energy, often in electronic circuits. This capatitor is commonly used in a variety of applications from filtering and bypassing signals, to decoupling power supply connections or helping to smoothen fluctuations in power supplies.

Type

The aluminum electrolytic capacitor is a polarized capacitor, meaning it has two electrodes, one positive and one negative. It works by storing energy as an electrical field between a pair of electrodes. Inside the capacitor are two aluminum foils, one of which has an anodizing layer to form the dielectric. When power is applied to this dielectric layer, an electric field is formed.

Construction

The aluminum electrolytic capacitor consists of two aluminum foils separated by an electrolyte. The positive electrode is made from one foil which has an anodizing layer, while the other foil acts as the negative electrode. Through a voltage, the positive foil attracts the electrolyte into it. This layer forms a dielectric, which stores the energy of the electric field. On the outside of the cap, two leads are attached for electrical connection.

Application

The aluminum electrolytic capacitor is used in many different applications. It is commonly used as a filter or bypass capacitor to help reduce electrical noise in a circuit. It can also be used to block direct current while allowing an alternating current to pass. Aluminum electrolytic capacitors are also used to separate signals from power sources, as well as to help smooth power fluctuations in power supplies. In addition, the capacitor can be used to help reduce voltage spikes, depending on its size and construction.

Working Principle

The aluminum electrolytic capacitor works by storing an electric charge between a pair of electrodes. When a voltage is applied, an electric field is created which attracts the electrolyte between the two foils. The dielectric formed this way is able to store and release the energy in the electric field. The capacitance of the capacitor determines the amount of charge it can store.

Conclusion

Aluminum electrolytic capacitors are widely used in a variety of applications from filtering signals to smoothing power supplies. Their construction consists of two aluminum foils as electrodes which are separated by an electrolyte. A voltage is applied to the electrodes to create an electric field, which then forms a dielectric. This dielectric is able to store and release the energy in the electric field, which is how the capacitor works.
