Aluminum Electrolytic Capacitors

An Aluminum Electrolytic Capacitor is an electrical device consisting of a cylindrical casing, an anode and a cathode terminal, a separator and an electrolyte (an ionic liquid or a porous medium). The two terminals are connected to a metalized, semi-permeable membrane. This type of capacitor is designed to store electrical charge and is used for a wide array of applications in a variety of consumer electronics such as televisions, radios and computers. Commonly used sizes range from 2.7V up to 27V.

The specific 277LBA250M2BD Aluminum Electrolytic Capacitor offers increased reliability and design flexibility. Utilizing its “Snap-in” mounting system, it can be easily installed and secured into their respective locations, reducing the need for additional parts. This allows for low profile designs, making for greater space saving potential. Its maximum ripple current capacity of 8.15A, makes the 277LBA250M2BD more than twice as efficient as its counterparts in its class. Containing either a 105°C or 125°C aluminum case, it is built to last in a variety of high temperature environments.

Field Applications

The 277LBA250M2BD Aluminum Electrolytic Capacitor find widespread usage in a variety of applications. Its inherent reliability and design flexibility make it a perfect candidate for circuit boards that engage in heavy-duty operations. Additionally, these capacitors are commonly used in electronic circuits that require heavy current rectification, noise filtering, power supplies, motor driving and DC to DC conversion circuits. When tasked with high frequency operations, or when dealing with signal suppression, the 277LBA250M2BD will serve as an invaluable asset.

Working Principle

An Aluminum Electrolytic Capacitor works by initially grounding its anode terminal and then supplying a voltage to the cathode terminal. This creates an electric field across the anode and cathode. The electric field causes ions to move from the anode to the cathode, while the electrolyte helps to spread the ions across the separator. This creates an electric charge on the anode and the cathode. This charge is maintained as long as the voltage is applied to the capacitor.

Conclusion

The 277LBA250M2BD Aluminum Electrolytic Capacitor is a reliable and design-flexible option for a variety of applications. Utilizing its “Snap-in” mounting system, it is easy to install and secure and is capable of supporting operation in high-temperature environments. Its high current carrying capacity, as well as its low profile design makes it a perfect candidate for DC to DC conversion, power supplies and motor drives. Its working principle is based on generating an electric field and allowing the ions to spread throughout the membrane.
