Aluminum electrolytic capacitors are energy-storage components that store electrical energy. They are widely used in modern electronics because of their high energy density. The UHE1A392MHT is an aluminum electrolytic capacitor designed for general purpose use. It’s a radial leaded capacitor that is particularly used in the audio industry due to its high reliability and temperature stability.

Application Field

The UHE1A392MHT is mainly used in 17-21 volts power supply circuits. It is often used in audio equipment such as amplifiers, microphones, sound cards, and mixers. The capacitor is also used in instruments and medical devices that require high voltage and low equivalent series resistance, such as defibrillators and ESU probes. As the capacitor has excellent damping capabilities it can also be used in automotive applications.

Apart from these applications, the UHE1A392MHT can also be used in electromechanical drives and circuit protection circuits. The capacitor can be used in motor drives and power supply standby circuits because of its high AC ripple current performance and low contact resistance.

Working Principle

The UHE1A392MHT is an electrolytic capacitor and works on the principle of electrolysis. It consists of two internal electrodes, which are separated by a dielectric oxide film. The dielectric acts as a barrier to reduce the leakage current by creating an electric field between the two electrodes. The electrode material in the capacitor is aluminum, which acts as the anode. The anode is then immersed in an electrolyte liquid, which provides the ions necessary for charge transfer. The process creates the charge polarization and stores electrical energy.

When a voltage is applied across the capacitor, an electric field is formed which causes the ions in the electrolyte to move towards the anode (positive electrode). This creates additional charges, resulting in a larger area of positive charge on the anode. At the same time, electrons migrate from the anode to the cathode, leading to a compact region of negative charge on the cathode. This process results in the storage of electric energy in the form of charge separation across the capacitors’ plates.

The UHE1A392MHT has a number of advantages that make it ideal for use in various applications. These include low ESR, high operating temperature, high ripple current capability, high energy storage capability, and excellent hydrophobicity. These features make the UHE1A392MHT an excellent choice for reliable capacitor applications.
