Aluminum electrolytic capacitors are solid electrolytic capacitors that use a solid organic polymer as an electrolyte electrochemical capacitor. It has the advantages of high capacity, long life, small volume and low price. The B41041A6158M is one such aluminum electrolytic capacitor, and its application field and working principle are described here.

Application Field

The B41041A6158M is an aluminum electrolytic capacitor mainly used in the coupling/decoupling filter, bypass, DC/DC converter and power module of switch power supply. It is suitable for the power supply circuit of various equipment, such as audio equipment, television sets, video recorders and computers.

Working Principle

When used, the B41041A6158M consists of two plates and a polymer electrolyte. A dielectric oxide membrane is formed on the anode plate by anodic oxidation, and the electrolyte acts as an insulator.

When a voltage is applied between the two plates, a capacitor is formed, and charge is stored electrostatically. The capacitance of the capacitor is determined by the size of the plates and the distance between them. The larger the plate or the smaller the distance, the larger the capacitance.

The electrolyte and the metal on the anode plate form a complex compound, the so-called dielectric oxide film, which is much thinner than the thickness of a hairspray, but is capable of withstanding a large voltage and has great electrostatic properties.

The capacitor\'s reaction time is short and it is able to discharge quickly. This makes it suitable for high-frequency circuits with high current or high instantaneous current with narrow pulse width. It is not as good as a specialized decoupling capacitor, but it is more than sufficient for uneven current distribution.

The B41041A6158M aluminum electrolytic capacitor can be used in a wide variety of applications such as power supply, bypass, decoupling, and filter circuits. The main advantage of this type of aluminum electrolytic capacitor is its relatively low cost and long service life.
