Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors possess large capacitance values in a small form factor. They are commonly used in power supplies, transmitters, amplifiers, and automated electronic equipment. This type of capacitor is one of the most inexpensive and commonly used varieties, and it is also one of the oldest types of capacitor.

B43501C2157M000 Application Field and Working Principle

The B43501C2157M000 aluminum electrolytic capacitors are printed aluminum-encapsulated electrolytic capacitors, and they are among the most popular and widely used capacitors for general-purposes. They are suitable for a wide range of applications, including circuits requiring high capacitance values in limited space, such as power supplies, amplifiers, and frequency converters. These capacitors are also ideal for use in electronic devices requiring high reliability and long life.

The B43501C2157M000 capacitors are constructed with an anode sheet of aluminum foil, a separator of paper, and a cathode of electrolytic material, and they are then encapsulated in plastic cases. The anode electrode and separator are polarized by a tantalum oxide layer, and the electrolytic material acts as the cathode. The aluminum foil acts as the anode electrode and is in direct contact with the electrolyte material.

The capacitor works by using the electrostatic attraction of the anode and cathode electrodes to store a charge between them. When the capacitor is charged up, the electric field between the anode and cathode creates a space charge that increases the capacitance. The electric field also maintains the charge, so the capacitor can maintain its charge under steady state conditions.

When the capacitor is discharged, the charge is dissipated as the electric field between the anode and cathode electrodes collapses, releasing the stored energy. This energy is dissipated as heat, and the capacitor returns to its original state until it is recharged. The cycle is repeated depending on the capacitor\'s capacity, temperature, and other factors.

In addition to the above characteristics, the B43501C2157M000 aluminum electrolytic capacitors also come with the benefit of a long life, ranging from 10,000 to 1,500,000 hours. They also possess high temperature stability over a wide range, and they are low-ESR and vibration-resistant. All of these qualities make them a great choice for applications that require long-lasting and reliable performance.

Overall, the B43501C2157M000 aluminum electrolytic capacitors are ideal for applications such as power supplies, amplifiers, and frequency converters due to their wide capacitance range, long life, and reliability. In addition to these qualities, they are also inexpensive and easy to find, making them one of the most widely used capacitors for general-purpose use.
