Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor (also known as a wet electrolytic, an electrolytic dielectric, an aluminum electrolytic pellistor, or a pillow capacitor) is an electronic component consisting of two electrodes, one of which contains a layer of oxide, that acts as a semiconductor. The oxide layer is usually applied on the surface of an aluminum foil. These capacitors are typically used for various types of applications such as signal processing, filtering, voltage regulation, energy storage, and coupling.

The 500C244U063DG2D series is an aluminum electrolytic capacitor with a rated voltage of 300V and rated capacitance of 0.25 uF. It is an ultra-small and low-loss Cu-shape type capacitor, which is characterized by its ultra-low ESR (equivalent series resistance), high ripple current, and high frequency characteristics. Its superior performance is the result of the use of anodic oxidation-coating technology and a self-healing, non-inductive, and non-polarized dielectric.

Application Field

The 500C244U063DG2D is primarily used for applications that require high-frequency characteristics, such as power strips, DC/DC converters, motor drives, power monitors, display drivers, and audio/video equipment. It is also used in switching power supply systems, LED lighting systems, solar power systems, and automotive electronics.

Working Principle

The 500C244U063DG2D capacitor utilizes a patented anodic oxidation-coating technology as its dielectric. This technology significantly reduces the natural capacitance variation of electrolytic capacitors at various temperatures compared to conventional capacitors. This allows 500C244U063DG2D capacitors to maintain their various characteristics over a wide temperature range. It also ensures the high-frequency characteristics required in many high-tech products, such as DC/DC converters, switching power supplies, and LED lighting systems.

The 500C244U063DG2D has a low ESR (equivalent series resistance) and can achieve high ripple current, which are both important properties for power electronic applications. For example, when employed in a switched mode power supply (SMPS), the capacitor helps to increase the efficiency of the power conversion process by reducing the voltage ripple and thereby increasing the power output of the system.

Conclusion

The 500C244U063DG2D aluminum electrolytic capacitor is an ultra-small and low-loss Cu-shape type component that can be used in a variety of applications. It utilizes an anodic oxidation-coating technology to reduce the natural capacitance variation of electrolytic capacitors at various temperatures. Its low ESR, high ripple current, and high frequency characteristics make it ideal for use in DC/DC converters, switching power supplies, LED lighting systems, and other power electronic equipment.
