Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitors that utilizes aluminum oxide layer formed on the surface of aluminum foils as the dielectric material. These capacitors have the highest volumetric efficiency among all types of capacitors, and are generally used as energy storage in numerous applications.

The B43858B5476M000 is a type of aluminum electrolytic capacitor. It is a miniature component, measuring 4 x 5.5 x 7.3 mm, with a capacitance of 47.6 uF, at 16.67 Vdc ripple current rating, a temperature range of -25 to 85 degrees Celsius, and a rated lifetime of 5000 hours at 85 degrees Celsius. Due to its small size, the B43858B5476M000 has become an ideal choice for use in applications where space is a critical factor.

Application Field of B43858B5476M000

The B43858B5476M000 is widely used for filtering and decoupling in a large variety of electronic circuits as well as in general power supply, such as in DC-DC converters, computer motherboards, storage systems, fuel injection systems, electronic clocks, audio and video players, and power amplifiers. It works particularly well in high frequency and wide dynamic range applications.

Working Principle of B43858B5476M000

The B43858B5476M000 consists of two components: an anode and a cathode. An aluminum foil is formed onto the anode with a thin layer of aluminum oxide as the dielectric material, providing the capacitor with a relatively high capacitance. The cathode is typically marked with a negative symbol (-) and an anode symbol (+). The capacitor is charged by providing electrical energy through the anode and cathode terminals, thus allowing an exchange of electrons across the dielectric layer.

When the capacitor is charged, the electrons from the anode are attracted to the cathode, thus establishing an electrical field across the dielectric layer. This electric field creates a capacitive effect, in which the capacitor stores energy. This stored energy is then released when a reverse current is sent across the capacitor, which results in a considerable voltage drop at the terminals.

The B43858B5476M000 has several advantages compared to other types of capacitors. Its miniature size allows it to fit in tight spaces, and its high capacitance makes it suitable for various applications, including filtering and decoupling. Its rated temperature range is also quite wide, making it ideal for use in areas with changing temperatures. Lastly, its rated lifetime of 5000 hours at 85 degrees Celsius ensures a dependable performance over time.

In conclusion, the B43858B5476M000 aluminum electrolytic capacitor is a versatile and dependable component that is widely used in various applications, such as filtering, decoupling, and power supply. Its small size and high capacitance makes it an ideal choice for use in high-frequency and wide dynamic range applications, particularly when space is limited.
