UVK2E3R3MED1TD Capacitors

Aluminum electrolytic capacitors (AECs) are one of the most commonly used electronic components in the electronic industry. They offer high capacitance and low equivalent series resistance (ESR), being thus widely adopted in various circuits, including high-power applications, power line filters, power supplies, and other. This article intends to provide an overview of the application fields and working principle of UVK2E3R3MED1TD aluminum electrolytic capacitors.

UVK2E3R3MED1TD aluminum electrolytic capacitors are widely used in various applications due to their unique characteristics. Among these, the most common application fields are listed below.

The UVK2E3R3MED1TD aluminum electrolytic capacitor consists of an aluminium foil that serves as the anode, a thin metal oxide layer on the foil that acts as the dielectric and a foil and paper combination that serves as the cathode. The metal oxide layer is formed by anodizing process where the aluminium foil is immersed in chemical electrolytes and then subjected to a certain voltage. This forms the dielectric layer with high insulating resistance.

The capacitance of the capacitor is determined by two main factors: the dielectric strength of the metal oxide layer and the size of the capacitor\'s electrode area. The reversed voltage rating is also an important factor that affects the capacitance. When a voltage greater than the rated value is applied to the capacitor, the electric field will breakdown the dielectric layer and cause the capacitor to fail. That is why it is important to select an appropriate capacitor for each application.

In operation, when a voltage is applied across the capacitor, a small electric field is produced across the dielectric layer. This electric field stores energy, which is measured as the capacitor\'s capacitance, and allows tiny electric charges to flow through the capacitor. When the voltage is removed, the energy stored in the capacitor can be discharged, or the capacitor can be charged up again with the same voltage to store more energy.

In conclusion, UVK2E3R3MED1TD aluminum electrolytic capacitors are widely used in various applications such as high-power applications, power line filters, power supplies and others. The working principle of these capacitors is based on electric field that develops across the dielectric layer, thus allowing tiny electric charges to flow through the capacitor. With their unique characteristics, these capacitors are key components in many electronic systems.
