Aluminum electrolytic capacitors are a type of capacitor that is used in a wide range of applications and which relies on a polarized electrolyte to store energy in the form of an electric field. The UUJ2D101MRQ1ZD is a cylindrically- shaped aluminum electrolytic capacitor manufactured by Panasonic. It features a low impedance design with 1.5 mm maximum operating temperature, a -40 °C minimum operating temperature, and a maximum voltage rating of 50 WV. It is rated to provide a practical capacitance of 0.068 mF± 20%.

The UUJ2D101MRQ1ZD is designed and manufactured based on a proven lead frame construction and is ideal for use in applications requiring the electrical characteristics of an aluminum electrolytic capacitor. Its two-terminal lead construction allows for easy mounting and electrical connection. The capacitor can also be soldered and directly mounted onto boards, eliminating the need for a separate mounting bracket. The UUJ2D101MRQ1ZD is typically used in DC-links, power supplies, and snubbers where a high capacitance value and low impedance are needed.

Aluminum electrolytic capacitors are constructed from layered aluminum and metalized paper sheets. 18 to 22 aluminum sheets are rolled up into a cylindrical form before being impregnated in a non-polarized organic liquid solution to form the polarized electrolyte. The solution is composed mostly of ethylene glycol, as well as a surfactant to provide the electrolyte with an even surface tension and viscosity. The electrolyte provides the capacitor with excellent surge current handling characteristics and allows it to maintain low leakage current.

The working principle of the UUJ2D101MRQ1ZD revolves around an applied electric field. When current is passed through the capacitor, electric charges collect at each terminal, creating an opposing electric field. The surface of the aluminum sheets is partially covered in a non-polar liquid, so the current is able to flow through freely, surfacing on the edges and creating a capacitor effect. This constant flow of current and the opposing electric fields is what stores the energy.

The UUJ2D101MRQ1ZD aluminum electrolytic capacitor is a versatile component with a wide range of applications. It is commonly used in medical instruments, automotive systems, and communication equipment. It is most suitable for applications such as DC-link, power FA converters, and motor drives. Additionally, its low impedance design, compact size, and long life make it an ideal choice for applications requiring excellent electrical characteristics over a wide temperature range.
