Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized electrochemical components utilized in a variety of electrical systems and equipment. They are used in many applications such as in power supplies, motor drives, avionics, telecommunication, automotive electronics, medical devices and lighting systems where their main function is to store and release electrical energy on demand. With its unique construction and design, aluminum electrolytic capacitors are able to provide high capacitance values within a low profile package, making them one of the best solutions for high-power density applications.

UKA1H220MDD application field and working principle

The UKA1H220MDD is a high-performance aluminum electrolytic capacitor developed by NIC components. It is a 20mF capacitor, with a 8.5mm radial casing, rated with an operating temperature range of -55°C to +105°C and a long useful life of 2000 hours. It has a wide range of uses, such as in motor drives, audio equipment, motor control circuits, UPS systems, DC-DC converters and battery-management systems.

The working principle of aluminum electrolytic capacitors are based on their internal construction which consists of an aluminum foil anode, a dielectric layer of oxide and a liquid electrolyte or solid polymer electrolytic. When a current is applied, the positively charged ions migrate to the anode, forming an oxide layer and this results in the charge polarization and generation of the capacitance. The electrolyte acts as the conductor between the two electrodes and due to its dielectric properties, this separation allows the charge to be stored for later use. This stored energy can then be released for use whenever needed.

Aluminum electrolytic capacitors have been a popular choice due to their low cost, highly efficient charge density and excellent AC ripple capability. The use of high quality raw materials and modern construction techniques ensure a highly reliable and long lasting product. With the UKA1H220MDD, NIC Components offers an advanced capacitor which is perfect for applications requiring high power and reliability.
