Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are types of capacitors that use anodized aluminum foil as one of the electrodes and a liquid or gel-like electrolyte as the other, and can be further sorted into axial-leaded, radial-leaded, snap-in and screw-terminal types. The 827LBB250M2CH is an aluminum electrolytic capacitor manufactured by Samwha Electric Co., Ltd, with excellent performance and long life.

Application Field

The 827LBB250M2CH aluminum electrolytic capacitor is mainly used in various applications such as in power supplies, light dimmers, inrush current limiters, automotive electronics, LED displays, radios, and other communication equipment. It performs reliably and efficiently in high voltage and high frequency applications. It can store and rapidly discharge a large quantity of electricity, and also help keep a steady flow of electric charge with its excellent capacitance stability.

Working Principle

The 827LBB250M2CH aluminum electrolytic capacitor consists of an aluminum foil etched with a large number of tiny cylindrical pores, and a liquid or gel-like electrolyte that is filled into the holes of the aluminum foil. When voltage is applied to the capacitor the liquid or gel-like electrolyte is polarized, creating a electric field that causes current to flow through it. This charge is stored in the metal surfaces of the tiny pores of the aluminum foil. The larger the number of pores, or ‘capacitance’, the more charges that can be stored in the capacitor.

The 827LBB250M2CH aluminum electrolytic capacitor also features excellent self-healing capability. An overvoltage or overcurrent event can cause gas discharge arcing inside the device, forcing the capacitor’s electrolyte to evaporate. The aluminum oxide layer on the aluminum foil will be regenerated by the electrolyte and the electrical charge stored safely, preventing the capacitor from physical damage.

Conclusion

The 827LBB250M2CH aluminum electrolytic capacitor is an excellent device that is ideal for many applications due to its high capacitance, long life, and reliable performance. Its excellent self-healing capabilities also makes it especially suited for applications where overvoltage or over-current events occur. It is thus a key component in many consumer electronic and automotive devices, and will continue to be used in many more applications in the future.
