Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components with a wide range of uses. Characterized by their high capacitance and reliability, they are an essential part of any modern electronics system. This article will provide a brief overview of the UPJ1C820MED1TD application field and working principle, as well as some other information.

Application Fields

The UPJ1C820MED1TD aluminum electrolytic capacitor is designed for use in power supplies, such as those used in medical and computing equipment, as well as high frequency circuits and other low noise environments. These capacitors can also be used for power filtering, frequency stabilization, and protection against high dV/dt (voltage overshoot). They are especially well-suited for applications that require high current and low equivalent series resistance (ESR).

Working Principle

At its core, the UPJ1C820MED1TD capacitor is comprised of an anode, a cathode, and two electrolytic layers. When connected to a power source, two opposite charges will build up on the two respective inner and outer sides of the capacitor. This charges creates a voltage between the two sides, creating a potential difference (also known as the “working voltage”) that is determined by the type of material used in the cathode and anode layers. The capacitors are furthermore protected against voltage overshoot with a dielectric layer.

Characteristics

The UPJ1C820MED1TD aluminum electrolytic capacitor is capable of withstanding a wide range of temperatures, from -25°C to +85°C, and has an excellent ripple current endurance. Additional characteristics include a low equivalent series resistance (ESR) of just 0.3Ω and a high capacitance of 820µF, allowing it to perform in high-power and high-frequency environments. Furthermore, its small size (8.3mm x 11.5mm) makes it a particularly attractive choice for use in small electronics systems.

Conclusion

The UPJ1C820MED1TD aluminum electrolytic capacitor is an ideal choice for a variety of power supply, high frequency, and low noise applications. With its high capacitance, low ESR, strong temperature endurance, and small footprint, this capacitor has all the features that one might need for a successful electric design.
