Introduction: What are Aluminum Electrolytic Capacitors?

Aluminum electrolytic capacitors, also known as alumina or alcryn capacitors, are one of the most commonly used capacitor types in electronic circuits due to their large capacitance values and low cost. These capacitors typically consist of a metalized aluminum foil that is rolled around a paper separator and soaked in an electrolyte solution.The aluminum electrolytic capacitor is part of the Metal Oxide Film Capacitor (MOFC) family, and is used for a wide range of applications where large capacitance values are required, such as high frequency filters, computer Motherboard\'s, Voltage Regulators, Transformers, Voltage Supplies, Amplifier Circuits, Oscillators, etc.

UHE1J681MHT6 application field and working principle

The UHE1J681MHT6 aluminum electrolytic capacitor is a high voltage capacitor with a long life (2000 hours @ 105°C) and high ripple current. It is a suitable choice for applications requiring a large capacitance value and high voltage rating. The UHE1J681MHT6 capacitor features a maximum working voltage of 200V and can handle a maximum temperature of -40°C to +105°C. It also has a 3mm diameter and has a pitch size of 2.5mm.The working principle of the UHE1J681MHT6 capacitor is based on the use of two electrical plates and an electrolyte solution. One of the plates is made from aluminum, while the other is made from a conductive material, such as tin or copper. The aluminum layer acts as the positive plate, while the other layer acts as the negative plate. When an electric current is applied to the capacitor, the positive aluminum layer absorbs electrons from the negative plate, storing a charge. This charge can be discharged when needed, providing an energy source for electronics circuits.

Conclusion

Aluminum electrolytic capacitors like the UHE1J681MHT6 are a reliable and inexpensive way to store energy in electronic circuits. They are capable of handling high voltages and temperatures, and are suitable for applications that require large capacitance values. The working principle of these capacitors is based on the use of two electric plates and an electrolytic solution, enabling them to store and discharge electric energy when needed.
