Aluminum electrolytic capacitors have become an important component of electrical, electronic equipment and various installations. UPW1C820MDD is one of the capacitors under this family. It has many applications in the industry, providing a number of benefits to electrical engineers. This article will discuss the application field and working principle of UPW1C820MDD.

Application Field of UPW1C820MDD

The UPW1C820MDD or Ultra Low ESR Product is an aluminum electrolytic capacitor, able to achieve the industry’s lowest ESR, or Effective Series Resistance. It is designed for use in a wide range of temperature conditions from -55 to +105 Celsius, making it ideal for many popular applications. The UPW1C820MDD is a multi-layer type capacitor, making it particularly suitable for next-generation semiconductor chips, as it can be fastened on the backside of the chips. This makes it an ideal component in various audio, video, automotive, and other applications that require a high level of small and lightness. The UPW1C820MDD is also well-suited to industrial DC power supply circuit and power supply circuit of high-adhesion mechanical equipment, as well as LED drive circuits, which require efficient energy conversion.

Working Principle of UPW1C820MDD

Aluminum electrolytic capacitors are capacitors with high power and are formed by an anode aluminum foil and two or more layers of aluminum oxide that act as the dielectric material. At the bottom of the dielectric layer, a special paper or film is affixed, allowing ions to pass through the whole capacitor. These ions will interact with the aluminum foil and form a double-layer structure - one part of it is a thin oxide layer, and the other part is a metal film. Electrons in the circuit effect the capacitor by the electrostatic field generated inside it, deforming the oxide layer and thus resulting in a change of capacitance.

UPW1C820MDD has an unique multi-layer structure - one side is made of metalized PET film, and the other side is made of aluminum foil. This specially designed construction leads to a device with multiple consistent layers of dielectric material and metalized PET film, which can significantly reduce ESR and parasitic inductance. This feature makes UPW1C820MDD suitable for the LED drive circuit and power supply circuits of high-end mechanical equipment, allowing a high-efficiency energy conversion.
