Aluminum electrolytic capacitors often referred to as “aluminum electros” are an essential component found in many electronic applications. They are characterized by their high capacitance, relatively low cost and relatively low equivalent series resistance (ESR). The UVR1E220MDD6TP is an aluminum electrolytic capacitor specifically designed to address the needs of applications requiring high capacitance and low ESR.

The UVR1E220MDD6TP – manufactured by Rubycon Corporation – is a miniature aluminum electrolytic capacitor with a rated capacitance of 220 µF and a working voltage of 10 VDC. It is solid polymer-encased in a miniature housing and features double-taped copper terminals with a built-in EMI Filter. The design features a wide temperature range (-40 °C ~ +105 °C).

The UVR1E220MDD6TP is widely used for decoupling, noise filtering, power supplies, and in many other general capacitor applications. The device is a popular and well-established component used in many of today’s consumer electronics, including both commercial and industrial grade designs. Because it is an aluminum electrolytic capacitor, it can provide a relatively high capacitance for a relatively low cost but with excellent stability and reliability.

The internal working principle of Aluminum electrolytic capacitors is based on a number of physical phenomena. To start with, there is a double electrical layer of charge, which is formed between the metal plates of the capacitor (the anode and the cathode). This double layer of charge is the result of the attraction between electrons and the metal plates. A voltage on the capacitor plates causes a relative movement of these electrons through the dielectric material.

The dielectric material that separates the metal plates will absorb some of the electrons, and have a resistance to the current flow. This dynamic resistance is known as the equivalent series resistance or ESR, and can have an adverse effect on certain applications. The UVR1E220MDD6TP is specifically designed to have a low ESR, which minimizes its impact on circuit performance.

The second physical phenomenon found in the aluminum electrolytic capacitor is capacitance. The capacitance is the ability of a material to store electrical charge temporarily. A higher capacitance results in more charge being stored for longer periods of time. The UVR1E220MDD6TP provides a high capacitance due to its construction of two coated aluminum plates with a non-conductive dielectric material in between.

The custom designed UVR1E220MDD6TP aluminum electrolytic capacitor is a powerful example of how electrical engineers can benefit from a modern capacitance technology. Its miniaturized design, ultra low ESR, wide temperature range and high capacitance make it suitable for a wide range of applications. Its ability to provide reliable and stable operation in challenging environments make it an ideal choice for high-power applications.
