Aluminum Electrolytic Capacitors

B41868A5228M is a high voltage aluminum electrolytic capacitor with built-in terminal device. It is mainly used in filter circuits and step-down transformers. In the filter circuits, it is designed to reduce noise in the audio signals. In the step-down transformers, it is used to reduce the voltage in the electric circuits.

Working Principle

The working principle of an aluminum electrolytic capacitor is based on Faraday\'s law of electromagnetic induction. It relies on the use of a non-metallic electrical insulating material, called electrolyte, which bonds between two metal plates. The two metal plates are usually made of either aluminum or tantalum. The aluminum plates have an oxide coating which serves as the dielectric for the capacitor. The oxide supports the electric field between the plates and creates insulation between them.

When a voltage is applied to the plates, a current is created. This current, in turn, causes electrons to be transferred from one metal plate to the other. This transfer of electrons causes capacitance to be created. This capacitance is responsible for forming the electric field between the two plates. The greater the applied voltage, the greater the capacitance.

The B41868A5228M is a type of Non-Polarized Aluminum Electrolytic Capacitor. These capacitors are simple in design and use the same principle as any electrolytic capacitor. The difference is that they do not require a polarized voltage for operation. This makes them attractive for use in various types of electronic applications.

Applications

The B41868A5228M is typically used as a filter and decoupling capacitor in switchgears, transmission lines, communication systems, and other power electronic circuits. Due to its high dielectric strength and low ESR (Equivalent Series Resistance) it is suitable for high voltage applications. It is also suitable for general purpose filtering, bypassing and blocking applications.

In addition to power electronic circuits, the B41868A5228M is often used as a filter capacitor in small DC-DC converters and DC/AC inverters. The capacitor’s high stability and low ESR make it suitable for these applications. The capacitor can also be used as a bypass capacitor in radio frequency circuits for EMI/RFI filtering purposes.

The B41868A5228M is also commonly used in automotive and aerospace applications. It is typically used as an energy storage device for spark generation, filter, and surge protection. It is also used as a decoupling capacitor in ignition systems to prevent interference with other ignition components.

The B41868A5228M is also used in various medical device applications. It is typically used as a filter capacitor for power supply in pacemakers. It is also used in ultrasound imaging systems to control the high-frequency power supply and reduce EMI.
