Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are components that use a process in which a thin oxide layer is formed on the anode from an electrolytic solution. This oxide layer acts as the dielectric in the capacitor. They are typically characterized by their volumetric efficiency, low equivalent series resistance (ESR), and long life. These capacitors have a wide range of applications, from filtering DC signals, energy storage, or as tuning elements in radio or TV sets. The UHV0J102MPD1TD aluminum electrolytic capacitor is one such component and is particularly well-suited for a number of DC power applications due to its high volumetric efficiency, long life, and low ESR.

UHV0J102MPD1TD Application Field and Working Principle

The UHV0J102MPD1TD aluminum electrolytic capacitor is a 10V, 2-pin, radial leaded component. It is rated for 0.1μF capacitance and 10K hours of life at 85°C. The product is rated up to 85°C, and has a high current carrying capability of 83mA at rated voltage and 85°C. With these specifications, the UHV0J102MPD1TD is ideal for use in DC switching power supplies, DC motors, DC automotive systems, motor start/stop circuits, board level decoupling, or wherever a small volume, high energy storage, long life capacitor is needed.

At the core of the capacitance between the anodes and the electrolyte is the double layer effect. This involves an electrical charge being built up with two layers that can be seen microscopically. The first layer is an oxide layer formed on the anode after the anode is oxidized by the electrolyte and the second layer is the larger layer of excess charge that is induced and held at the interface of the two layers. This double layer effect is why aluminum electrolytic capacitors typically have a larger capacitance than other types of capacitors and why they age slowly.

The UHV0J102MPD1TD utilizes an anode made up of a pure aluminum strip annealed with an oxide film as the main electrode. The electrolyte is then spread throughout the anode and forms a compound oxide film when it is exposed. The capacitor package is filled with an inert gas, such as nitrogen, to insulate the capacitor and to reduce the ESR. The body of the capacitor is made of epoxy resin which serves as the insulating body and to secure the contacts, axial leads, and other components to the body.

The UHV0J102MPD1TD provides an efficient solution to a wide range of DC power applications with its high volumetric efficiency, long life, and low ESR. With its wide temperature range and compact size, the UHV0J102MPD1TD is a reliable, inexpensive, and easy to use capacitor able to meet the requirements of many DC power applications.
