Aluminum electrolytic capacitors (AECs) are the most commonly used type of capacitor in electronic applications. The B43504A127M62 is one such AEC and is used in many applications, such as for filtering and decoupling circuits and for buffering noise and line regulation. In this article, the application fields and working principle of this particular AEC type will be discussed.

Application Fields

The B43504A127M62 is a miniaturized, low-impedance aluminum electrolytic capacitor which is dedicated for use in spaces of limited areas, such as miniature and microcircuits. This AEC type is ideal for applications such as for powering small digital circuits, and also provides excellent low ESR values for a very low equivalent series resistance. Its small size and low price make it an ideal component for low-cost consumer-grade electronics, which is why it is one of the most commonly used AECs in the industry.

The B43504A127M62 is also used in RF and microwave applications, where its small size and low equivalent series resistance are critical components in maintaining the necessary performance. This AEC type is not only suitable for these specific applications, but is also capable of operating under high-temperature and corrosive environments. Additionally, its extended life shelf-life makes it a reliable component even in application fields which exposed it to heavy-duty usage.

Working Principle

An aluminum electrolytic capacitor consists of two metal plates (called anode and cathode) sandwiched between an electrolyte-filled container, which is the negative plate. The electrolyte absorbs a flat charge between the two metal plates, and this creates an electrostatic field between them. Since the quantity of electrons in each plate is equal, if a voltage is applied to one of the plates, it causes the electrons to flow from one plate to the other. This charge flow creates an electric current, which is the basis of capacitive electrical energy storage.

In the case of the B43504A127M62, the plates are coated with oxide and their respective connections with the electrical circuit are made through a sealing wax. The electrolyte inside the capacitor consists of an organic solvent and a high concentration of acidic salts. The combination of electrolyte and metallic plates creates an electrostatic field, whose capacity is determined by the size of the capacitor. In this way, electric energy is stored in the capacitor and is released whenever necessary.

The B43504A127M62 is designed to withstand extended periods of time at high temperatures and within a wide range of operating conditions. This allows it to maintain its performance in several different application fields. In addition, its longer life-span, low equivalent series resistance, and small size make it an ideal capacitor for a wide range of consumer and industrial grade electric and digital electronic applications.
