B43866C2156M Datasheet/PDFAluminum electrolytic capacitors are polarized electrolytic capacitors consisting of two aluminum foils separated by a thin (typically 1-4 µm) layer of oxide. A eutectic alloy of aluminum and manganese is normally used for the anode; the cathode is typically covered with activated carbon powder. The electrolytic capacitor was the first type of capacitor developed and it retained its dominance up until the invention of the ceramic capacitor in 1950. Although their capacitance values are much lower than that of ceramic and film capacitors, they feature significantly higher volumetric capacitance (capacitance/volume) than ceramic, film, or paper capacitors.
The B43866C2156M aluminum electrolytic capacitor is a polarized E-Cap with molded cases and solid electrolytic construction with SnPb termination finish. It is designed to operate in turbulence-free conditions, offering a long life and reliable performance. The capacitor comes with increased ripple current capability for higher frequencies, allowing users to create applications which have a higher frequency of operation (up to 500 kHz).
The B43866C2156M features a long life of up to 3000 hours, a capacitance range of 10 µF to 4700 µF, and a voltage rating up to 450 VDC. It comes with male/female terminals for easy mounting, and its Leakage-Current-Dissipation (LCD) factor can reach up to 7 mA. This aluminum electrolytic capacitor also comes with an increase in ripple current of up to 106 mA for longer life of application.
When it comes to applications, the B43866C2156M aluminum electrolytic capacitor is an appropriate choice for intermediate frequency (IF) filters, high frequency DC-DC converters, and other general electronic equipment. It is suitable for providing high levels of AC performance in any of these applications. In IF filters, this capacitor is used to reduce the noise and provide a stable alternating current (AC) output. It is also used in DC-DC converters, providing stability and low noise levels when switching the current.
The working principle of the B43866C2156M aluminum electrolytic capacitor is based on the operation of two thin aluminum layers separated by a thin layer of electrolytic solution. When a voltage is applied to the capacitor, electrons move through the electrolytic solution, creating an electric current. This current helps to store energy in the form of an electric field inside the capacitor. The capacitor can then discharge its energy when the voltage is removed, allowing current to flow without loss and stability to be maintained.
In conclusion, the B43866C2156M aluminum electrolytic capacitor is an ideal choice for a range of applications, including IF filters, high frequency DC-DC converters, and other general electronic equipment. It features a long life of up to 3000 hours, a capacitance range of 10 µF to 4700 µF, and a voltage rating up to 450 VDC. Its high levels of AC performance, increased ripple current capability, and LCD factor make it a great choice for these applications. The working principle of this capacitor works by the movement of electrons through the electrolytic solution to store energy in the form of an electric field.
