Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a diverse range of electrical and electronic products. They are most suitable for filtering, energy storage, power factor correction and decoupling applications. The UBC1A221MNS1GS aluminum electrolytic capacitor is a product of the United Brands Corporation and is designed to provide reliable performance even in demanding conditions.

Application Field

The UBC1A221MNS1GS aluminum electrolytic capacitor is an AC-rated capacitor suitable for a wide range of power supply applications, including line-by-line regulation, power factor correction, circuitry isolation, and/or decoupling. It is also suitable for automotive applications, higher power factor LED lighting, and LED driver power supplies. Additionally, this capacitor can be used in making EDLCs (supercapacitors) due to its large capacitance.

Design and Construction

The UBC1A221MNS1GS aluminum electrolytic capacitor is constructed with a wet-fill electrolyte, a polypropylene dielectric, and an anodized aluminum case. This construction makes it resistant to shock, vibration, temperature fluctuations, and other environmental influences. The capacitor also features a liquid-tight seal, which prevents leakage of electrolyte and other contaminants. The capacitor’s rated operating temperature range is -40°C to +85°C.

Capacitance and Voltage Ratings

The UBC1A221MNS1GS aluminum electrolytic capacitor is available in a range of capacitance and voltage ratings, from 220 uF to 20,000 uF and from 6.3 to 750 VDC. The rated leakage current of the capacitor is equal to or less than 0.02 mA, and it has a nominal lifetime of 2000 hours.

Working Principle

The working principle of the UBC1A221MNS1GS aluminum electrolytic capacitor is based on the principle of capacitance, which is the ability of a capacitor to store electrical energy in an electric field. In this capacitor, the electric field is created by a pair of metal plates that are connected to a dielectric material, such as the polypropylene film used in this capacitor. When a voltage is applied across the plates, the electric field causes charges to accumulate on the surface of the plates, thereby creating an electric potential difference between the plates. This electric potential difference stores electrical energy in the capacitor until the voltage is removed.

Conclusion

The UBC1A221MNS1GS aluminum electrolytic capacitor is an ideal capacitive load for a wide range of power supply applications. Its rugged construction, wide range of capacitance and voltage ratings, and reliable performance even in extreme environments make it well suited for demanding applications. Its working principle is based on the same principles as other capacitors and allows it to store and release electrical energy when necessary.
