Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of electrochemical capacitor with an anode that is made out of a pure aluminum foil with an etched surface. It has an oxide layer electrolyte, usually of an organic solvent, covering the etched surface. Its cathode is generally defined by a printed circuit board onto which it is soldered. A wide variety of forms of electrolytic capacitors exist, however the most popular and cost effective remain tantalum, aluminum electrolytic, ceramic disc, and plastic film.

UWX1H010MCR2GB Application Field and Working Principle

The UWX1H010MCR2GB is a type of aluminum electrolytic capacitor which falls under the family of POMAX Aluminum Electrolytic Capacitors. These components are mainly used in passive electronic circuits for general purpose DC filtering, energy storage, or power conditioning applications. They are cost-effective solutions for filtering and rectification in medium-to-high volume commercial applications.

This component is a two-terminal, non-polarized electrolytic capacitor. It consists of an anode plate which is sealed to the case by means of a metallic strip or foil along with the electrolyte. At the same time, a cathode terminal is connected to the case which also acts as the anchor for the anode. In addition, a dielectric layer is produced on the anode plate which increases capacitance. This layer is a result of a chemical reaction between the anode foil, the electrolyte, and an electric field.

The electrolytic capacitors UWX1H010MCR2GB feature a high capacitance per unit volume, low losses, and a wide temperature range. The capacitors possess a maximum operating voltage rating of 10V, a capacitance of 1000μF, a rated ripple current of 12 mA, and a life expectancy rating of 1000 hours. Furthermore, the device has a +/-20% capacitance tolerance rating, a temperature range of -40°C to 85°C, and a rated working frequency of 120Hz.

The capacitance of an electrolytic capacitor is determined mainly by the thickness of the dielectric oxide layer and the area on which the anode and cathode contact each other. For UWX1H010MCR2GB, the capacitance increases with the applied voltage until the maximum operating voltage is reached where the breakdown voltage of the dielectric film is exceeded. As the temperature of the capacitor increases, the capacitance decreases and the lifetime decreases as well.

Apart from its low cost, another significant advantage of the UWX1H010MCR2GB is its high capacitance to volume ratio, which is up to 1,000 μF per unit volume. This makes it much more cost-effective to use these components in applications requiring a large amount of total capacitance. Additionally, the component also has an extremely low effective series resistance (ESR) which contributes to its wide frequency response and better performance in power conditioning applications.

In conclusion, the aluminum electrolytic capacitor UWX1H010MCR2GB is suitable for use in high-quality signal and power conditioning. It is a cost-effective solution in applications requiring a large amount of total capacitance and its wide temperature range and low ESR make it ideal for use in high-performance applications.
