Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are components mainly used in devices for filtering, buffering, and smoothing of AC signal, DC voltage smoothing, decoupling and so on in electronic and electronic equipment. It is usually used with resistors, inductors and other components to form various circuits with different functions. Aluminum electrolytic capacitor refers to the capacitor with liquid electrolyte, which uses aluminum foil as its positive electrode plate, and uses a thin insulating layer of aluminum oxide film as its dielectric, which is filled with liquid electrolyte.

Classification of Aluminum Electroytic Capacitors

Aluminum electrolytic capacitors are generally divided into two categories: general-purpose aluminum electrolytic capacitors and high-temperature aluminum electrolytic capacitors.

• General-purpose aluminum electrolytic capacitors are made of aluminum foil as electrode plate and coated with electrolytic aluminum oxide on it as dielectric. The electrolyte can be generally divided into liquid and solid electrolyte. It has the characteristics of large capacitance, low resistance, good self-healing properties and high volumetric efficiency, so it is widely used in power electronic equipment, instrumentation, etc.
• High temperature aluminum electrolytic capacitors are developed on the basis of general-purpose aluminum electrolytic capacitors. There are generally two kinds of electrolytes: ethylene glycol electrolyte and silicone oil. High temperature Aluminum electrolytic capacitors have the characteristics of high temperature resistance and outstanding self-healing process, which can meet the special requirements of higher working temperature in some special occasions.

Working Principle of B43456A9478M000

The working principle of B43456A9478M000 can be divided into two parts: charging and discharging.

• Charging.When power is supplied to the capacitor, the electric field starts to increase in the capacitor, and electrons are attracted by the electric field. As a result, the capacitor\'s terminal voltage increases, the capacitor is charged and reaches its rated voltage.
• Discharging. When disconnect with the power supply, the capacitor starts to discharge. Since the capacitor consists of two different materials on each side, electrons will flow in the opposite direction of the electric field between the two plates, and the capacitor gradually dissipates its energy.

Conclusion

B43456A9478M000 is a high temperature aluminum electrolytic capacitor with high temperature resistance and outstanding self-healing performance. It can be widely used in industrial control, automotive electronics, video equipment, communication equipment and other fields. Its working principle is related to the charging and discharging of the capacitor, which relies on the electric field between the two plates of the capacitor for the flow of electrons.
