Aluminum electrolytic capacitors feature variable capacitance and are composed of two aluminum plates that are separated by dielectric oxide film and soaked in electrolyte. Part number 500D108M035GH2 is a high-quality aluminum electrolytic capacitor manufactured by a reliable brand. In this article, we will discuss the application field and working principle of this capacitor.

Application Field

Aluminum electrolytic capacitors like the 500D108M035GH2 capacitor are mostly used in DC-DC power converters and large power supplies in order to reduce ripple noise. Moreover, these capacitors may be used in charging systems, such as battery chargers, as well as in uninterruptible power supply systems. They are also used in rugged electronic systems, as they are able to withstand extreme temperature swings, humidity, vibration, and shock. Furthermore, this type of capacitor is used in inverters for converting direct current to alternating current, LED lighting, audio systems, automobile electronics, and many other applications.

Working Principle

An aluminum electrolytic capacitor consists of two electrodes separated by a dielectric layer of oxide film. It is a polarized electrolytic capacitor, which means one electrode is anode and the other is a cathode; therefore, current can only flow in one direction. The anode is made of aluminum foil with a thin oxide coating, and the cathode consists of a solid or liquid electrolyte. The dielectric layer is formed when an electric current is passed through the electrolyte, which oxidizes the surface of the aluminum foil and forms the dielectric layer. This aluminum foil is then rolled and inserted in the capacitor can and polarized depending on the voltage.

The working principle of an aluminum electrolytic capacitor is simple. When a voltage is applied across the two electrodes, the voltage difference causes electrons to move from the anode to the cathode. This movement of electrons produces an electric field across the anode and the cathode. As a consequence of this electric field, a charge builds up on the anode and the cathode, thus creating capacitance. The magnitude of the capacitance of an aluminum electrolytic capacitor is determined by the surface area of the aluminum foil, the thickness of the dielectric oxide layer, and the distance between the two electrodes.

In conclusion, capacitors are one of the most widely used components in electronic devices, and 500D108M035GH2 is a high-quality aluminum electrolytic capacitor with many applications in many areas. It is used to reduce ripple noise in power supplies and DC-DC converters, reduce voltage peaks in uninterruptible power supply systems, and convert direct current to alternating current in inverters. Additionally, its working principle is simple and involves the creation of an electric field between two electrodes and the formation of an oxide layer on the surface of the aluminum foil.
