Aluminum electrolytic capacitors are one of the most common types of capacitors widely used in electronic product designs. These capacitors are known for their large capacitance and extremely low equivalent series resistance (ESR). The UPJ1V820MED is a widely used aluminum electrolytic capacitor that is manufactured by Panasonic.

The UPJ1V820MED, which is an axial leaded device with a cylindrical body and non-polarized components, boasts an impressive capacitance of 820uF. The device also has a guaranteed maximum operating voltage of 50V, a maximum ripple current of 6.24A and a working temperature of -40°C to +105°C. It is a radial leaded aluminum electrolytic capacitor with a radial lead pitch of 5.08mm, making it easy to integrate with certain types of application circuits.

In terms of its application field, the UPJ1V820MED is most commonly used in power management for computer, telecommunications and consumer electronic products. It is also used for decoupling and filters in unconventional applications such as amplifiers, DC/DC converters, voltage regulators, switching regulators, motors and lamps.

This capacitor is surprisingly cost-efficient due to its high performance characteristics. The UPJ1V820MED is also known for its excellent fatigue life and very low ESR making it suitable for quite a wide range of applications.

As for its working principle, the UPJ1V820MED consists of two metal foils that have been wound together and then sealed inside a container which was partially filled with an electrolytic solution. The electrolyte creates an electric field that stores electrical energy in the form of an electric double layer. When voltage is applied across the terminals of the capacitor, the electric double layer is suppressed and charges up to its rated capacitance.

The dielectric used in this device is manufactured with Aluminum Oxide which is placed between the metal plate electrodes, forming an electrochemical layer. When current is passed through the capacitor, the metal plates are polarized, creating an electric field. This helps to reduce the leakage current without the need for additional components.

To ensure that the capacitor is able to withstand high levels of stress and strain, the UPJ1V820MED is welded using a patented welding technology developed by Panasonic. This helps to reduce mounting space, minimize leakage current and ultimately increase its safety and reliability.

In summary, the UPJ1V820MED is a high performance aluminum electrolytic capacitor manufactured by Panasonic. It has a guaranteed capacitance of 820uF, a maximum operating voltage of 50V and a temperature range of -40°C to +105°C. It is often used in power management applications for computer, telecommunications and consumer electronic products and is also known for its low ESR, excellent fatigue life and welded construction. This helps to reduce mounting space, minimize leakage current and increase safety and reliability.
