Aluminum Electrolytic Capacitors

A capacitor is an electrical device that stores electric charge. In general, it consists of two conductive plates separated by an insulating material called a dielectric. Aluminum electrolytic capacitors are capacitors in which one of the conductive plates is made of a metal foil that is typically aluminum and the other is made of a metal oxide. They are the most widely used type of capacitor because of their very high capacitance, which is much higher than other types of capacitors. Aluminum electrolytic capacitors are used in many applications, but the most widely used are in power supplies, power conversion, noise reduction, and high voltage switching.

B41890A7188M application field and working principle

The B41890A7188M is an aluminum electrolytic capacitor suitable for applications requiring high capacitance and long life, such as power supplies. It features a capacitance of 188mF and a rated voltage of 400 VDC. It is also resistant to vibration, shock, and temperature variations, and has a long shelf life of up to 10 years.

The B41890A7188M works by utilizing the different electrical properties of metal and metal oxide. The conductive metal foil forms one plate of the capacitor, while the metal oxide forms the other. The metal foil provides high electrical conductivity and the metal oxide provides high capacitance. When a voltage is applied across the two plates, electrons are transferred from the metal foil to the metal oxide. This creates a negative charge on the metal foil and a positive charge on the metal oxide. This creates an electric field between the charges, which stores energy.

The B41890A7188M capacitors are used primarily in power supplies because of their high capacitance and long life. They can also be used in motor drives and ignition systems. They are also suitable for applications requiring high reliability or those where replacement intervals are long. In addition, they are also suitable for high-voltage circuits since they provide excellent isolation.

The B41890A7188M capacitors also have some drawbacks. They are more expensive than other capacitors, and they have a limited voltage rating, which means they cannot be used in higher voltage applications. They are also prone to heat and vibration, and thus require special precautions when handling and mounting.

In summary, the B41890A7188M capacitor is an aluminum electrolytic capacitor suitable for applications requiring high capacitance and long life. It features a capacitance of 188mF and a rated voltage of 400 VDC. It is resistant to vibration, shock, and temperature variations, and has a long shelf life of up to 10 years. The B41890A7188M capacitors are used primarily in power supplies, safety systems, motor drives and ignition systems, and are also suitable for high-voltage circuits.
