Aluminium Elecrolytic Capacitors

Aluminum electrolytic capacitors, also called tantalum electrolytic capacitors, are capacitors that use two aluminum foil plates separated by a dielectric oxide film as conductive plates, and are characterized by a combination of high capacity and high volumetric efficiency.

The B41827A5687M is a form of aluminum electrolytic capacitor, and provides a high capacity output for a relatively small size. The capacitor features a range of advantages as its robust construction is tolerant to temperature changes and associated with good electrical performance. The capacitance of the capacitor ranges from 0.1 F to 1000 F.

Application Fields

The B41827A5687M can be found in various applications, such as power supplies, audio equipment, control systems, and communications systems. In power supplies, the capacitor is used for AC line filtering, smoothing, and energy storage, and boosts the current in start up. The capacitor can also be seen in audio equipment, specifically used for signal crossover, and as coupling devices.

Working Principle

The B41827A5687M capacitor uses aluminum oxide and organic solvent as the dielectric medium. An anode and a cathode are connected respectively to two aluminum foils coated with manganese dioxide and serve as part of the terminal. The anode is attached to the positive pole and the cathode is connected to the negative pole. The organic solvent forms a compact film on the surface of the aluminum foil and acts as a dielectric medium between the two electrodes. When a DC voltage is applied to the capacitor, a positive charge moves to the anode and a negative charge to the cathode, forming an internal electric field.

When the applied voltage is high enough, the electric field strength is strong enough to absorb the electrons from the anode and transport them away. The accumulated positive charges on the anode cause the dielectric medium to break down, increasing the capacitance of the capacitor. As the voltage decreases, the electric field becomes smaller, and the capacitance of the capacitor decreases until it is completely turned off.

In addition, its dielectric medium also has other features, such as self-healing, which allows the capacitor to recover from a minor electrical short circuit. This helps to increase the life span of the capacitor, with a typical life expectancy of 10,000 hours.

Conclusion

The B41827A5687M aluminum electrolytic capacitor is a highly efficient and reliable device that can be used to meet the needs of various applications. Its robust construction and ability to self-heal make it a great component for use in audio equipment, control systems, and power supplies.
