The Aluminum Electrolytic Capacitor is a component consisting of two aluminum foils with an insulating layer between them, having a high capacitance and large withstand voltage. The UVZ1E4R7MDD1TD is an Aluminum Electrolytic Capacitor with a capacitance of 9.2μF, operating voltage of 200V, and a temperature rating of -25°C to +85°C. It is mainly used in power supplies, DC power lines and audio systems.

Aluminum electrolytic capacitors are widely used in various applications due to their large capacitance, large voltage, low loss, and small size. They are mainly used in audio systems, power supplies, DC power lines, and other circuits with large amplitude and fast response. For example, in power supplies, they are used to filter the switching signals, absorb spikes, and maintain the DC output voltage within a fixed range. In DC power lines, they are used for the decoupling of signals, protection against overvoltage, harmonic absorption, and transient suppression.

The working principle of UVZ1E4R7MDD1TD Aluminum Electrolytic Capacitor is based on the electrolyte solution inside the capacitor. Two dissimilar metals are immersed in an electrolyte solution, forming an anode and a cathode. When a voltage is applied, an electric field is generated between the two metals, which generates a polarization. This electric field produces an electric double layer (EDL) between the two electrodes, thus forming a charge separation and a built-in electric field. This built-in electric field generates a capacitance, which allows for the electrical energy storage. The capacitance of an electrolytic capacitor is determined by its physical properties, such as the capacitance of the liquid electrolyte, the pore volume of the anode, and the thickness of the diaphragm.

In conclusion, the UVZ1E4R7MDD1TD Aluminum Electrolytic Capacitor is a component with high capacitance, large withstand voltage, and wide application. It utilizes the properties of electrolyte solution inside the capacitor to create a built-in electric field and thus generate capacitance. It is mainly used in power supplies, DC power lines, audio systems, and other circuits with large amplitude and fast response.
