B43851A9335M000

Aluminum electrolytic capacitors are among the most popular types of capacitors available. These devices are used in a wide variety of applications, often where cost is a factor, due to their relatively low cost compared to other capacitor types. The B43851A9335M000 is an example of such a device.

The B43851A9335M000 is an aluminum electrolytic capacitor with a capacitance of 330µF and a rated voltage of 400 VDC. It is a radial leaded device, meaning it has leads that extend radially outward along its circumference, with a width of 10 mm, a height of 13.2 mm and a lead hole diameter of 2.3 mm. The leads are solderable and are made of tin-plated copper.

Aluminum electrolytic capacitors utilize thin aluminum foil as the conductor material, which is coated with an oxide layer for insulation. The oxide layer is formed by applying a voltage to the capacitor, which causes a chemical reaction to occur at the surface of the foil. This reaction creates a layer of oxide, which acts as an excellent insulator.

The active surface of the foil is coated with an electrolyte, usually a mixture of water and ethanol. The electrolyte contains ions, which fill the pores between the oxide layers, forming a single dielectric layer covering the foil. The electrolyte also acts as an ionic conductor, providing a path for electrons between the two layers of aluminum foil. The combination of insulating oxide layer and conductive electrolyte creates the capacitor dielectric.

B43851A9335M000 aluminum electrolytic capacitors have a wide variety of applications ranging from audio circuits to power supply filtering. As a low impedance capacitor, it’s commonly used in the output stages of audio amplifiers. It is also commonly used to reduce peak-to-peak ripple current in power supplies. In addition, it’s suitable for spike suppression in LED driver circuits and filtering inductive noise in motor control applications.

The B43851A9335M000 aluminum electrolytic capacitor is a low-cost, low-ESR choice for a wide range of applications. Its relatively low impedance and wide operating temperature range make it a suitable choice for audio, power supply, and motor control applications. Its radial leads also make it easy to mount in through-hole applications.
