Aluminum Electrolytic Capacitors - E80D350VNN272AQ25T Application Field and Working Principle

Aluminum electrolytic capacitor, also known as electrolytic capacitor or "electrolytic", is a polarized capacitor which uses an electrolyte to achieve a larger capacitance than other types of capacitors. It is composed of two aluminum foils with oxide layer as its dielectric materials, with one side as anode and the other as cathode. Between two foils is a paper separator which is soaked in electrolyte. The E80D350VNN272AQ25T (from Siemens Kirkhi Line) is an aluminum electrolytic capacitor. This section will discuss its application field and working principle.

Application Field

The aluminum electrolytic capacitor E80D350VNN272AQ25T has many applications. It is widely used in power electronic systems, such as switch power supplies, high frequency inverters, industrial robots, battery chargers, etc. It can also be used in various switching circuits, signal processing circuits and pulse circuits. In addition, it has been widely adopted in audio systems because of its low cost and high efficiency.

Working Principle

The working principle of an aluminum electrolytic capacitor starts with a pair of aluminum foils, one anode and the other cathode. In between the two foils is a very thin insulating oxide layer which acts as the dielectric. However, the oxide layer is so thin that it cannot handle significant voltages. This is why electrolyte is introduced between the two foils, the electrolyte compensates for the insulating properties of the oxide layer by providing ionic conductivity. When a voltage is applied between the two foils, a current flows through the electrolyte, which allows to strengthen the electric field and thus increasing the metal film capacitance of the capacitor.

The benefits of using an aluminum electrolytic capacitor are numerous. This type of capacitor is able to store and release electrical energy quickly and can handle significant voltages. The capacitance of aluminum electrolytic capacitors can be as high as one thousand times of traditional capacitors. In addition, aluminum electrolytic capacitors are cheap, lightweight, and easily produced in large quantities.

Conclusion

The aluminum electrolytic capacitor E80D350VNN272AQ25T is widely adopted in many electronic systems, and is especially efficient for high current and high voltage applications. Its relatively large capacitance, low cost, and light weight make it a popular choice for many applications. In addition, the electrolyte present in this type of capacitor improves its dielectric properties and allows for high voltage carry capacity. This overview of the application field and working principle of an aluminum electrolytic capacitor has shown the advantages this type of capacitor has over other types of capacitors.
