Introduction to Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is any of a variety of different types of electrical capacitors that use an aluminum oxide as its main dielectric. The aluminum oxide layer is generally very thin in order to provide the necessary insulation to protect the electrical components within the capacitor. This type of capacitor has a much higher capacitance than traditional solid electrolytic capacitors. The high capacitance of aluminum electrolytic capacitors makes them well suited for many applications where a very high capacitance is needed, such as for filtering high frequency signals.

MVY50VE471MM17TR Application Field and Working Principle

The MVY50VE471MM17TR aluminum electrolytic capacitor is designed for medium frequency, line filtering applications. It is a radial leaded, screw terminal aluminum electrolytic capacitor with a capacitance of 1000 F. This capacitor is capable of operating from -25°C to +85°C.

The working principle of the MVY50VE471MM17TR aluminum electrolytic capacitor is governed by its internal construction. At its core, the capacitor consists of two metal plates (anode and cathode) separated by an oxide layer. The anode and cathode plates are connected to an external power source, which provides a potential difference between them. The oxide layer between the plates acts as an insulator, preventing any current flow between them. When an alternating current or voltage is applied, the field between the anode and the cathode alternately stores and releases energy. This alternating field causes a capacitance to develop between the two plates, which results in the capacitor storing electrical energy in the form of an electrical charge. As the capacitance of the capacitor increases, the amount of energy stored in the capacitor also increases.

In the case of the MVY50VE471MM17TR capacitor, the electrolyte used is a bi-polar electrolyte, which consists of a combination of a solution of a hydrogen ion donor (eg, sulfuric acid, glycerol, oxalic acid, phosphoric acid, etc) and a hydrogen acceptor (eg, boric acid, potassium hydroxide, lithium hydroxide, etc). This electrolyte solution is used to form the thin oxide film between the two metal plates. As electricity is applied to the capacitor, it passes through the oxide film, allowing the capacitor to store electrical energy.

Conclusion

The MVY50VE471MM17TR aluminum electrolytic capacitor is a highly efficient, high capacity capacitor suitable for medium frequency line filtering applications. This capacitor\'s high capacitance makes it an ideal choice for filtering high frequency signals. Its construction consists of two metal plates separated by an oxide layer, which is then filled with a bi-polar electrolyte. When electricity is applied to the capacitor, the alternating current or voltage causes the field between the anode and the cathode to alternately store and release energy, resulting in the capacitor storing electrical energy in the form of an electrical charge.
