Aluminum electrolytic capacitors are a type of capacitor that primarily uses an aluminum oxide film as a dielectric. The capacitor typically consists of two aluminum foil plates, with the oxide film between them acting as the dielectric. The type of oxide film used plays a crucial role in determining the capacitance and performance characteristics of the device. Capacitance is determined by the area of the two plates, their separation, and the type of film.

B41505A8478M002 is a type of aluminum electrolytic capacitor with a variety of applications. It is a polarized capacitor with a convenient form factor, allowing it to fit in very tight places and making it particularly suitable for use in high-density circuits. Due to its excellent characteristic of high temperature performance, it is often used in temperature-sensitive circuits such as switching power supplies, linear regulators, and switching regulators.

The working principle behind the B41505A8478M002 aluminum electrolytic capacitor relies upon a process called anodic oxidation of aluminum foils. In this process, an electric current is passed through an electrolyte solution between two sheets of aluminum foil. The current decomposes molecules in the electrolyte solution, and the resulting oxidation process deposits an oxide layer on the aluminum foil. This oxide layer acts as the dielectric for the capacitor.

The oxide layer is extremely thin, with a thickness of just a few nanometres, which makes the oxide layer very efficient at creating capacitance. This oxide layer also withstands high temperatures, allowing the capacitor to be used in circuits with temperatures up to 125°C. The small form factor, high temperature performance, and high capacitance makes the B41505A8478M002 aluminum electrolytic capacitor an ideal choice for a variety of applications, including power supply filter circuits, automotive electronic circuits, measurement instrumentation, and much more.
