Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in power electronics, wireless communication, medical applications, automotive electronics, and other electronics industries. The URZ1V220MDD1TD is one of the most popular aluminum electrolytic capacitors available on the market today.

The URZ1V220MDD1TD is a surface mount, radial-leaded aluminum electrolytic capacitor with a rated voltage of 125V, a capacitance of 320μF, and a capacitance tolerance of ±20%. It has a temperature range of -40°C to +105°C, leakage current of <0.03CV or 3.6μA ( whichever is lower ) , and a rated ripple current of 4A @ 105°C. The case size of the URZ1V220MDD1TD is ø6.8mm x 11mm. Moreover, its dielectric type is aluminum oxide and its electrolyte type is organic semi-solid electrolyte.

The URZ1V220MDD1TD is designed for use as a general-purpose capacitor in a wide variety of applications such as power supplies, voltage regulators, DC-DC converters, inverters, motor drive circuits, and automotive electronics. Its high capacitance, low ESR, and long-term reliability make it suitable for use in these applications. Moreover, its high ripple-current handling capability makes it ideal for use in electrical circuits with high-frequency or high-temperature variations.

The working principle of an aluminum electrolytic capacitor is based on the fact that the aluminum oxide layer that is formed when the aluminum electrode reacts with the electrolyte acts as an electrical insulator. This layer is known as the dielectric and it is what allows the capacitor to store charge. When voltage is applied across the terminals of the capacitor, the ions in the electrolyte are drawn towards the electrodes and are deposited onto the aluminum oxide, forming an electric double layer. This electric double layer creates an electric field across the capacitor, which is what allows the capacitor to store electric charge.

The URZ1V220MDD1TD offers good performance, long-term reliability, and a wide range of applications. It is an ideal choice for general-purpose power supply, voltage regulator, DC-DC converter, and motor drive circuit applications, as well as automotive electronic applications.
