Aluminum Electrolytic Capacitors - UPW1H821MHD6 Application Field and Working Principle

Aluminum electrolytic capacitors are a type of capacitor that are specifically designed to perform in high-height, high-temperature and other extreme operating conditions. The most popular type of aluminum electrolytic capacitor for these applications is UPW1H821MHD6. This capacitor is available in a range of sizes and voltages, and offers an extensive range of capacitance values, from 0.1pF to 2.2µF.

Application Field

UPW1H821MHD6 is an ideal choice for a wide range of applications, including communication systems, industrial automation and many other electronic equipment. The capacitor’s ability to deliver currents at far higher than normal levels has made it especially suited for high-voltage and high-current applications, where its small size and high power dissipation rating provides a cost-effective solution.

The UPW1H821MHD6 is frequently used in DC-DC power supplies, such as the one used to power laptops and other portable electronic equipment. It is also a popular choice for use in AC-DC converters, high-frequency switching power supplies, automotive electronic systems and high-voltage isolation applications.

Working Principle

Aluminum electrolytic capacitors are composed of two parallel metallic plates coated with an electrolytic solution. The positive plate is made of aluminum foil and the negative plate is made of an insulating material like paper or ceramic. The two plates are separated by an ionized electrolyte solution, which is a combination of small organic molecules like acetic acid and water.

When a voltage is applied across the capacitor, electric charges are generated at both metallic plates, causing the positive plate to become positively charged while the negative plate becomes negative charged. An electric field is created between the two plates and a capacitor is formed. Thus, an electric current is able to travel from one plate to the other, resulting in the storage and release of electrical energy.

An important feature of the aluminum electrolytic capacitor is its ability to withstand very large AC and DC voltages. This means that it can be used in circuits which require very high power levels or high voltage. The UPW1H821MHD6 is especially suited for these applications, due to its robust design.

Conclusion

The UPW1H821MHD6 aluminum electrolytic capacitor is a versatile and reliable component with a huge variety of applications. Its ability to withstand large AC and DC voltages makes it perfect for high-voltage and high-power applications, while its small size and high power dissipation rating ensures it is cost-effective. The working principle of the electrolytic capacitor makes it an ideal choice for a range of industrial and communication systems.
