Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components that take advantage of the properties of electrolytic materials as a way to achieve large capacitance with relatively small devices. They are usually used in DC power supplies, energy storage devices, and signal processing circuits. Aluminum electrolytic capacitors are available in a variety of forms, including axial lead, snap-in, screw terminal, and more. The E80D250VNN103AA30T is a type of aluminum electrolytic capacitor.

Application Field

The E80D250VNN103AA30T is a surface-mount aluminum electrolytic capacitor with a voltage rating of 250V and a maximum temperature of 85°C. This capacitor is best suited for application in inverters for solar panels, motors, deflected cathode ray tubes (CRTs), fuel cells, and oxygen concentrators. It is also suitable for applications in telecom, IT, medical, industrial, and automotive controls systems. The E80D250VNN103AA30T can be used in circuits where high in-rush current, ripple current, and energy storage requirements need to be met. It is suitable for switching power supplies, rectifier circuits, and other high-frequency applications.

Working Principle

Aluminum electrolytic capacitors like the E80D250VNN103AA30T are composed of two aluminum foils separated by a layer of electrolytic material. The internal electrolyte provides charge storage and ionic conduction between the electrodes. The E80D250VNN103AA30T has an anode made of anodic aluminum oxide that forms a positive-charge bearing surface on the inside of the capacitor. The capacitor also has a cathode made of aluminum foil, which is connected to an outer connecting plate. The electrolyte serves as an ion conductor, allowing only positive ions to flow. This allows for the buildup of charge on the fixed anode, effectively storing energy in the capacitor.

The anodic aluminum oxide film in aluminum electrolytic capacitors is extremely thin and highly porous, allowing for a higher capacitance-voltage rating. Since the E80D250VNN103AA30T is an SMD or surface-mount type component, it can be quickly and easily mounted on board or other surfaces using surface mount technology. This makes it especially attractive for high-volume production in a variety of applications.

The E80D250VNN103AA30T has a wide temperature range of -55°C to +85°C, making it ideal for high temperature applications. It also features a low ESR (equivalent series resistance) and long life. The E80D250VNN103AA30T is ideal for a variety of applications where performance, reliability, durability, and safety are desired.

Conclusion

The E80D250VNN103AA30T aluminum electrolytic capacitor has a wide variety of uses, from solar and energy storage to automotive and telecom systems. It is easy to mount and has a wide temperature range, making it suitable for high temperature applications. It also has a relatively low ESR and a long life span. These features make the E80D250VNN103AA30T aluminum electrolytic capacitor an excellent choice for electrical and power applications where reliability, performance, and safety are necessary.
