Aluminum electrolytic capacitors have been widely used in electronics equipments and components. B41231D6688M000 is one type of this capacitor. It has been designed for military and mixed signal applications. It is qualified to military standard. This capacitor is specifically designed with long lifetime and high peak current for high temperature environment, and it also can operate in temperatures down to -55℃.

The B41231D6688M000 aluminum electrolytic capacitor is used in applications such as audio, portable systems, memory systems, DC/DC converters, AC/DC converters, headsets, headphone amplifiers, etc. It has the advantages of good ESR, low leakage current, and high temperature stability. The robust aluminum case and terminals of this capacitor provide excellent heat dissipation and contact stability.

The working principle of an aluminum electrolytic capacitor is based on the Faraday law of electrolysis. This states that when two metal plates are immersed in an electrolytic solution, an electric current will cause a displacement of ions in the solution. This results in an accumulation of ions on the plates. This accumulation creates an electric field between the two plates which is known as the electrical capacity of the capacitor. The amount of electrical capacity is determined by the surface area of the plates, the distance between them, and the type of electrolyte solution used.

The B41231D6688M000 aluminum electrolytic capacitor is constructed with two aluminum foil electrodes that are rolled into a cylinder of a specific diameter. The two plates are separated by a dielectric layer, which can be a paper or plastic impregnated with an electrolyte solution. On the outside is a layer of insulating paper and metal foil wrapped around the cylinder. This design helps to reduce the leakage current and the capacitance of the capacitor. When a voltage is applied between the two electrodes, the electric current flows through the electrolyte solution and the electric field is formed across the two plates which stores energy for later release. The dielectric layer acts as an insulator and prevents the charges of the opposite polarity from rapidly discharging.

The B41231D6688M000 aluminum electrolytic capacitor can withstand an extreme range of temperatures, and provides high stability and long operational life. It also provides high capacitance in the same physical size of the capacitor. It is used in circuits that require long life and high reliability, such as memory systems and audio applications.
