Aluminum electrolytic capacitors are the most popular type of electrolytic capacitors. They are also known as polarized capacitors and are widely used in a variety of applications. One example is the URZ1E100MDD capacitor, a radial leaded, aluminum electrolytic capacitor with non-solid electrolyte and a rated voltage of 100V. This type of electrolytic capacitor is especially suitable for use in high-frequency or high-voltage applications, such as in power supplies, voltage decoupling, and in filtering circuits.

The construction of an aluminum electrolytic capacitor is relatively simple. It consists of an anode made of aluminum, a solid or liquid electrolyte, and a cathode foil. The anode and cathode are separated by a dielectric layer known as the insulation layer. This layer is typically made of a mixture of organic-solvent based electrolytes and metal oxides that are sprayed onto the anode. The dielectric layer helps to block the flow of current between the anode and cathode, while allowing the electric field to pass freely across the layers.

The working principle of an aluminum electrolytic capacitor is based on the process of electrolysis. When a voltage is applied to the capacitor, an electric field is created across the anode and cathode. This electric field causes a reaction, called electrolysis, to occur between the electrolyte and the aluminum anode. As a result, positive ions of aluminum are created at the anode and flow to the cathode, creating a capacitor.

The URZ1E100MDD aluminum electrolytic capacitor has a relatively low ESR (Equivalent Series Resistance) and is capable of handling currents up to 100mA. This makes it ideal for use as a smoothing capacitor and in applications such as power supplies, voltage decoupling, or audio filtering. Another advantage of the URZ1E100MDD is its long life span; the manufacturer guarantees its lifetime to be up to ten years (at rated capacitance and rated voltage).

In conclusion, the URZ1E100MDD aluminum electrolytic capacitor is a widely used device, capable of handling high frequency and high voltage applications. Its low ESR, long lifetime, and high capacitance make it an ideal choice for many applications. It is important to remember that due to its polarized nature, it must be wired correctly when used in a circuit. Furthermore, it is recommended that the capacitor is regularly checked for signs of corrosion or any other damages, in order to ensure its continued performance.
