Aluminum electrolytic capacitors are widely used in power supplies, output filters, switching circuits and many other applications. One of them is the LGL2G151MELZ25 type capacitor, an electrolytic capacitor with an anode made of aluminum oxide film and a cathode made of aluminum. This type of capacitor is used in many electronic circuits, including audio systems and power supplies. In this article, we will look at the application fields and working principle of the LGL2G151MELZ25 electrolytic capacitor.

Application Field

The LGL2G151MELZ25 is a high-performance aluminum electrolytic capacitor. It is widely used in high-voltage applications such as power supplies and switching circuits. The working voltage of this type of capacitor is 50V-500V and the capacity is from 1mF to 15mF, with a long surge endurance capacity. This makes the LGL2G151MELZ25 an ideal choice for high-voltage transient suppression and filtering. The capacitor is also used in audio systems, in combination with other types of capacitors, to provide high-quality audio signals.

Working Principle

Aluminum electrolytic capacitors work on the principle of electrochemical double layer. The capacitor consists of two electrodes, one of which is made of aluminum and the other is a conductive electrolyte. A thin film of aluminum oxide is formed between the two electrodes, which acts as an insulating layer. When a voltage is applied, the aluminum oxide film will store charge and become charged. The positive charge is stored in the aluminum layer and the negative charge is stored in the electrolyte. When the applied voltage is removed, the stored charge will slowly dissipate or discharge. The rate at which the charge dissipates is dependent on the size and type of capacitor, and the resistance in the circuit.

Conclusion

The LGL2G151MELZ25 is an aluminum electrolytic capacitor designed for high-voltage applications such as power supplies, switching circuits and audio systems. It has a good surge endurance capacity and is capable of storing and releasing charge over a long period of time. The working principle of this type of capacitor is based on the electrochemical double layer, which stores charge and charge and releases it slowly when the voltage is removed.
