Aluminum Electrolytic Capacitors -- B41896C5477M000 application field and working principle

Aluminum electrolytic capacitors are the most common type of capacitor used in electronics. This is because they offer a high capacity for storing electrical energy in a small amount of space, as well as the ability to withstand high temperatures and maintain their capacitance over a wide range of frequencies. As such, they are used in a wide variety of applications, such as high-frequency circuits, power supply filters, and signal-coupling networks.

One important type of aluminum electrolytic capacitor is the B41896C5477M000 series. These capacitors are designed to thrive in extreme-high temperature environments ranging from -55 to +165 °C, making them ideal for use in applications such as automotive electronics, power systems, and telecommunications. Moreover, they have a very long service life expectancy, with maximum capacitance tolerance reaching up to ± 30 % (20,000 hours at 105 °C).

In terms of its working principle, an aluminum electrolytic capacitor stores electrical energy in a capacitor housing, which is made up of two metallic plates separated by a polarised aluminium oxide layer. When a voltage is applied to the capacitor’s leads, an electric field is created between the two metallic plates, which is displaced to the aluminium oxide layer. This alters the permittivity of the oxide layer, causing it to store positive and negative energy in the capacitor housing.

In addition, aluminum electrolytic capacitors are known for their low ESR (equivalent series resistance) values. This is due to the fact that the metal oxide sandwiched between the capacitor’s metallic plates has a particularly low innate electrical resistance. In comparison to other capacitor types, aluminum electrolytic capacitors are able to transmit energy more efficiently, as there is less resistance to impede the flow of electrons.

To conclude, aluminum electrolytic capacitors are an important class of electrical components, and the B41896C5477M000 series is an excellent example of this versatile type of capacitor. Thanks to its low ESR values, high temperature tolerance, and long service life, these capacitors are a great option for use in a variety of low- to high-power applications.
