Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors provide one of the most economical solutions for handling higher voltages and/or currents than standard capacitors. With their low cost and long life cycle, aluminum electrolytic capacitors are used in a wide variety of applications such as consumer electronics, power supplies, and automotive systems. Moreover, they can provide large capacitance values for high power applications. In this article, we’ll take a closer look at the characteristics and applications of the popular UPS2A4R7MDD aluminum electrolytic capacitor.

UPS2A4R7MDD Characteristics

UPS2A4R7MDD stands for 2.2µF 5mm x 5.5mm / 16V Aluminum electrolytic capacitor. It is a small size aluminum electrolytic capacitor consisting of a round can; dielectric material; and a foil, anode and cathode construction.It has a rated voltage of 16V and a tolerance of -20% to +50%. The operating temperature range lies between -40 °C to +85 °C and the ripple current rated at 10kHz, 105°C is 2.09A.

UPS2A4R7MDD Application Field and Working Principle

UPS2A4R7MDD aluminum electrolytic capacitors are suitable for filtering and bypass elements, as well as electronic ballast for fluorescent lamp and circuit stabilization applications in a wide range of products.As a stabilized power source, aluminum electrolytic capacitors are used to ensure stable power supply voltage and low noise. The aluminum electrolytic capacitors are also used in power supply, hydropower, and automobiles to act as filters.Aluminum electrolytic capacitors are constructed with a solid dielectric layer of an aluminum oxide film on a pure aluminum foil, with a liquid electrolyte that serves to counterbalance the internal electrical pressure. This construction provides higher capacitance values over standard ceramic capacitors and also allows the capacitors to easily handle higher voltages and currents.Due to the construction of an electrochemical system, aluminum electrolytic capacitors are polarized meaning that the electrical characteristics of the capacitor will be affected if the polarity is reversed. The soundness of electrolytic construction can be affected by high temperature, high humidity, and high voltage, so it is important to ensure proper storage and handling.

Conclusion

UPS2A4R7MDD aluminum electrolytic capacitors are efficient and reliable components suitable for a wide range of applications including filtering and bypass elements, circuit stabilization, and electronic ballast for fluorescent lamp applications. The capacitors are inexpensive and have a long life cycle, which make them ideal for high power applications. In order to ensure reliable operation, proper storage and handling are key.
