Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors with aluminum foil and heavy oxidized film as electrodes. They have advantages such as large capacitance, low cost, low leakage current and long service life. They are mainly used in areas such as filters, oscillators, buffers and decoupling, and power supplies for computers or other components of electronic equipment. The most common type used is the can-type capacitor, which is widely used in general-purpose electronic circuits.

B41821B9476M000 Application Field and Working Principle

The B41821B9476M000 is an electrolytic capacitor with a rated temperature range of -40°C to +105°C, and is widely used in many applications. It is constructed with an aluminum capacitor element with a long block shape and molded plastic case. The device features a high ripple current capability and long useful life. It has an excellent frequency and temperature characteristics for use in noise reduction circuits.

The working principle of B41821B9476M000 is based on the same underlying technology as all other electrolytic capacitors – an electrically insulating dielectric is formed when two thin aluminum foils are coated with a manganese dioxide layer, then rolled and separated. When an electrical field is applied, a hydrated layer of oxide forms on the aluminum surface, forming a polarized capacitor. This layer acts as an insulator and stores the electric field, allowing for a temporary storage of energy.

Due to the low dc leakage current and excellent temperature and frequency characteristics, B41821B9476M000 capacitors can be used in various applications such as bypass or coupling filters, power supply stabilization and noise reduction. Their features also make them suitable for low voltage power supplies, DC-DC converters, UPS systems, switching power supplies, automotive electronics and industrial electronics.

In addition, these capacitors have a wide variety of design parameters that can be tailored to meet specific customer requirements. For example, capacitors can be designed with multiple anodes, capacitance range, pulse strength, voltage levels, frequency response, temperature range, and mounting options. This makes them an ideal choice for most applications.

In conclusion, B41821B9476M000 aluminum electrolytic capacitors are highly versatile and can be adapted for use in a wide range of applications. They offer excellent dc and low frequency leakage current, excellent temperature and frequency characteristics, pulse strength, and a wide range of design parameters. This makes them a popular choice for many electronics.
