The B43888A9476M000 capacitor also has a wide range of industrial application fields. For instance, it can be used in amplifier equipment, audio frequency equipment, micro-controller systems, medical equipment, communication systems and high-frequency power supply switching product. It is characterized by small size, low loss, good ripple absorption effect and electromagnetic resonant suppression capability. This type of aluminum electrolytic capacitor is also the optimal choice for coupling, bypassing and reforming circuit.

Working Principle

The B43888A9476M000 aluminum electrolytic capacitor is made up of two overlapping metal foils that serve as the two plates of the capacitor. One metal foil serves as the anode and is covered with a thin layer of semiconductive materials layer that has a large number of through-holes with a controllable electrolyte barrier. The other metal foil serves as the cathode. There is a layer of insulation, or dielectric, between these two metal foils. The distance between these two metal foils is extremely small, and when an electric current passes through them, electrostatic charge can be stored between these two metal foils. This electrostatic charge constitutes the capacitance of the aluminum electrolytic capacitor.

When an AC signal is applied to the aluminum electrolytic capacitor, the metal foil acts as a capacitor. The AC signal will generate an electrical field between the two metal foils and create an electric current. The size of the current varies with the frequency of the AC signal and the impedance of the capacitor. The frequency of the AC signal determines how large the electric current will be. The impedance is determined by the size of the capacitance of the aluminum electrolytic capacitor.

For high frequency AC signals, the impedance of the capacitor decreases as the frequency increases and the capacitance increases. The impedance will eventually reach a maximum at a certain frequency, and no further increase is possible. This is why the aluminum electrolytic capacitor has a maximum capacitance. The same principle applies to the voltage rating of the aluminum electrolytic capacitor; the rated voltage determines the maximum voltage that can be applied to the aluminum electrolytic capacitor.

In conclusion, the B43888A9476M000 aluminum electrolytic capacitor has a wide range of application fields, be it industrial or electronics. Its working principle makes it an ideal choice for coupling, bypassing and reforming circuit in order to ensure that the voltage and current are accurately applied in a circuit.
