Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors are electrical components that store energy using the electrostatic field between two metallic surfaces, usually plates of aluminum foil. In comparison with other capacitor types, electrolytic capacitors offer the highest capacitance values per unit volume or mass. As a result, they are commonly used in battery-powered devices, where a large amount of capacitance can be stuffed into a small space. They are also used in low-profile applications, such as device switching, power supplies, audio amplifiers, signal coupling networks, and decoupling from power supply noise.

The B41692A5688Q7 is an aluminum electrolytic capacitor developed and produced by Panasonic. It is a miniaturized aluminum electrolytic capacitor with a rated voltage of 250VAC and a nominal capacitance of 680uF. It is also rated for operations up to 105 degrees Celsius.

The application field of the B41692A5688Q7 is quite diverse, as it can be used for a variety of applications such as filtering, power conversion, and power protection. It is especially popular for switching power supplies, motor control, and power filters. Furthermore, they are most often used as buffer capacitors in LED lighting power applications.

The working principle of an aluminum electrolytic capacitor is based on the fact that aluminum is the only metal that forms an insulating oxide layer on its surface. This oxide layer acts as the capacitor dielectric. The element is then polarized so that one plate is positively and one plate is negatively charged. When voltage is applied to the element, electricity can flow through the thin oxide layer. Additionally, the capacitance of aluminum electrolytic capacitors can be easily adjusted by adding or removing the amount of electrolyte solution and by the temperature of the solution.

In conclusion, the B41692A5688Q7 is a miniature aluminum electrolytic capacitor developed by Panasonic that is suitable for a variety of applications such as filtering, power conversion, and power protection. Its working principle and features offer distinct advantages, such as the ability to easily adjust the capacitance by modifying the electrolyte and temperature of the solution.
