Aluminum electrolytic capacitors are based on a construction in which aluminum anode foil, typically etched, serves as alternate plates with a ceramic layer and organic film as the dielectric. The cathode is formed on the exterior of a heat resisting glasslike cylinder. Electric charges are transferred to the foil by means of the electrolyte, a solution of ethylene glycol and various salts. Aluminum electrolytic capacitors are suitable for circuits requiring anywhere from 0.1 microfarad to 470,000 microfarads.

The B43505E2227M82 is an aluminum electrolytic capacitor. It is a radial-leaded flat capacitor designed for use in applications with a working voltage of 250VAC and a maximum capacitance of 0.047 µF. The device is constructed from an aluminum electrolyte, etched aluminum anode foil and an epoxy resin end cap that is filled with aluminium powder. It is hermetically sealed and protected against oxidation and moisture, making it suitable for use in damp environments.

The main advantage of aluminum electrolytic capacitors is their ability to today\'s high-voltage, high-current power applications. The large capacitances of aluminum electrolytics make them excellent candidates for bridge circuits, power factor correction, power conditioning, and other power supply applications. The low cost relative to other types of capacitors also add to their appeal. Additionally, they possess significant capacitance and offer fast response times that are ideal for pulse-width modulation, phase-shift modulation, and frequency compensation capacitors.

The working principle of aluminum electrolytic capacitors is quite simple: by transferring a charge from the aluminum anode foil to the epoxy resin end cap, electric charges are stored. The electrolyte acts as the conductor between the plates, and the ethylene glycol and salts provide a low-resistance medium for the current. This charge is held by the capacitor until the electric field between the plates is removed. Upon removal, the electrical charge dissipates rapidly, releasing stored energy.

The B43505E2227M82 aluminum electrolytic capacitor is designed for use in power applications such as power conditioning, power factor correction, bridge circuits, pulse-width modulation, phase-shift modulation, and frequency compensation capacitors. Its rated voltage of 250VAC and maximum capacitance of 0.047 µF make it ideal for such applications. The device is hermetically sealed and protected against oxidation and moisture, making it suitable for use in damp environments.
