Aluminum electrolytic capacitors, also known as electrolytic capacitors, are widely used in electrical and electronic circuits. The UHW2A391MHD6TN is a type of aluminum electrolytic capacitor that is generally used in high-current application fields and has a working principle based on Faraday’s law of electrolysis.

The UHW2A391MHD6TN is a polarized capacitors which means it has a positive lead and a negative lead. It is composed of two aluminum foil sheets, which acts as the electrodes, that are separated by an electrolyte. The upper foil is etched with a series of grooves to form a large number of conducting cells which increases the surface area. The two aluminum foil terminals are connected to the two ends of the electrolytic solution.

When a potential difference is applied across the terminals, the electrolyte undergoes a reaction called “electrolysis” which establishes an electric double layer, containing charged particles between the two electrode foils. The amount of charge stored by this electric double layer is proportional to the applied voltage and is known as the capacitance of the capacitor.

The UHW2A391MHD6TN is typically used in high current applications where capacitors with large capacitance are required. Its maximum capacitance is 2000 μF, and it has an operating temperature range of -40°C to +105°C and ripple current of 3.6 A @ 100kHz. This makes it an excellent choice for use in circuits that require high levels of current with a high level of stability. It is also suitable for power supply applications such as computers, motor drivers and power supplies.

The UHW2A391MHD6TN is also highly reliable. Its thick aluminium foil allows it to withstand high levels of vibration and shock without any degradation in performance. Its low leakage current means it is suitable for long-term use in circuits, and it has a long shelf life due to its low rate of evaporation of the electrolyte.

In conclusion, the UHW2A391MHD6TN aluminum electrolytic capacitor is an excellent choice for use in applications requiring high levels of current. It has a high capacitance, a wide operating temperature range, and reliable performance. The thick aluminum foil also lends it a high level of shock and vibration resistance making it suitable for use in applications that must be able to withstand harsh conditions.
