Aluminum electrolytic capacitors are capacitors in which the aluminum oxide layer acts as the dielectric, and electrolytic solution of aluminum for both electrodes. They have high capacitance-to-volume ratio, are fast to react and are relatively inexpensive to manufacture. The UVZ1H682MRD aluminum electrolytic capacitor is a small case-sized electrolytic capacitor with high capacitance. It is designed to provide large capacitance at a low voltage and demands low mounting space.

The UVZ1H682MRD is a polarized aluminum electrolytic capacitor, available in two standard sizes, with a maximum capacitance of 10,000µF. It features an operating temperature range of -40°C to +105°C and a rated voltage of up to 35V. Its cylindrical can is sealed in epoxy resin with a brass rivet and a white terminal tag. It provides high capacitance at high ripple currents, offering the capability of handling high capacitance in a small space.

The aluminum electrolytic capacitors have a structure consisting of an anode, a dielectric, a cathode, and a separator. Inside the aluminum electrolytic capacitor, the anode is a rolled sheet of aluminum foil with a chemical conversion layer of oxide film on its surface. This oxide film acts as the dielectric material in the capacitor, providing insulation between the two electrodes. The cathode is composed of a metal electrolyte, which is usually an alloy of aluminum or zinc with other elements. The metal electrolyte allows current to flow across the oxide film and provides temperature compensation for the capacitor.

The meaning of the letter “U” in the UVZ1H682MRD aluminum electrolytic capacitor is the mounting type dielectric, which is a non-solid polymerized film. The “V” means radial leads, “Z” indicates the category of military components. The “1H” represents a unique product identification code. The “682” shows the capacitance and tolerance of the aluminum electrolytic capacitor. The “MRD” is the marking code of the specific series.

The working principles of an aluminum electrolytic capacitor are relatively simple. When voltage is applied to the capacitor, the electric field of the applied voltage causes the metal electrolyte of the anode to ionize, creating an electric current. This current passes through the oxide film, creating an electric charge on both the anode and the cathode of the capacitor. Since the electrolyte has a relatively high electrochemical stability, the charge is stored and held as long as the voltage continues. Once the voltage is removed, the electric charge dissipates quickly.

The UVZ1H682MRD aluminum electrolytic capacitor is a highly reliable component for applications in consumer electronics, telecommunication equipment, industrial and medical electronics, automotive electronics, data processing and measurement applications. It supports extremely low ESR levels and high ripple current. Thanks to its high capacitance, it can be used to filter noise in communication lines, provide power supply buffering, as well as to store and release energy. It is also suitable for decoupling and bypass, as well as synchronous sampling of amplifiers and other applications.

In summary, the UVZ1H682MRD aluminum electrolytic capacitor is a reliable component with a high capacitance and low voltage. Its structure consists of an anode, dielectric, cathode, and separator that allows electric current to flow across the oxide film and provides temperature compensation for the capacitor. The working principle is relatively simple and it is widely used in consumer electronics, telecommunication equipment, industrial and medical electronics, automotive electronics, data processing and measurement applications.
