Aluminum electrolytic capacitors are a type of capacitor which predominantly consists of two aluminum foils, which are separated by a thin layer of electrolyte. In contrast to ordinary capacitors, aluminum electrolytic capacitors have a much higher capacity per unit volume, and are used in applications such as audio applications, dc-dc conversion, pulse power supply, and many other applications where high capacity and small size are important factors. The working principle of aluminum electrolytic capacitors can be explained as follows.

The two aluminum foils of the capacitor are separated by a thin layer of electrolyte, which acts as an insulator. A voltage is applied across the aluminum foils, the electrolyte breaks down, generating an electric double layer on both specialized internal electrodes, creating an electrostatic field.

When a voltage is applied to the capacitor, positive ions from the electrolyte attach themselves to the aluminum foil called the anode. The electrons arriving from the anode travel through the circuit, and attach to the other aluminum foil, called the cathode. At the same time, the positive ions arriving at the cathode, also travel through the circuit, and attach to the anode. This creates a charge in the capacitor, which can be used for a variety of applications, such as power supply filtration, audio applications, and dc-dc conversion.

In addition to the charge storing capabilities of aluminum electrolytic capacitors, they also provide high ripple currents, high volumetric efficiency, and low equivalent series resistance (ESR). Furthermore, aluminum electrolytic capacitors are also able to handle high voltage and high temperatures without any performance loss.

The UHE1H4R7MDD1TD is a type of aluminum electrolytic capacitors, suitable for applications such as audio applications, dc-dc conversion, pulse power supply, and many other applications where high capacity and small size are important factors. It is a radial-leaded aluminum electrolytic capacitor, with an operating temperature range of -35 to +85°C, capacitance range of 4.7µF, and rated voltage of 63V. It features low equivalent series resistance, which promotes high ripple currents, and high volumetric efficiency, making it an ideal choice for high performance, high frequency applications.
