Aluminum electrolytic capacitors (AECs) are the most commonly used type of capacitor, they are based on the mechanism of electrolytic double layer dielectric. The double layer dielectric effects are made behaviors when aluminum plate and oxide component are used in an electrolytic capacitor. The aluminum plate is the anode in the aluminium electrolyte capacitor and, there is an electrolyte between the aluminum plate and the separator, where the separator is the cathode.An oxide layer is formed on the aluminium plate surface, this oxidation is promoted by Passing a direct current through the aluminium plate. The thicker oxide layer increases the capacitor value. AECs have excellent wide temperature range stability. The leakage current of the AEC is very low so that it has a good reliability, and hence it is widely used in various applications. B43456A9228M000 are aluminum electrolytic capacitors, with capacitance of 0.47µf, the rated voltage of 25V, and their working temperature range of -55℃~105℃. The main application fields of B43456A9228M000 are;

• Power supply filtering: The B43456A9228M000 can be used in a power supply system for filtering, where they can be used to reduce the ripple of DC output and to improve the power supply system’s power quality.
• Vibrator device: The vibrator is an important device in many electronic circuits, and B43456A9228M000 can be used to provide the gate control pulse, and in radio communication equipment, it also used as frequency stability circuit.
• Resonance circuit: In the electronic resonance circuit, B43456A9228M000 can be used to change the input signal, This application is important for radio communication, because it has a detection modulation circuit.
• Timing circuit: Capacitors are widely used in electronic timing circuit, and B43456A9228M000 can also be used as timer in the circuit.

Now, let’s take a look at its working principle; Capacitors are made up of two conductive plates that are separated by an insulating material. The AECs have a thin layer of oxide film on the anode. The oxide layer is formed when current passes through the anode, and when the current stops, the oxide layer can’t be re-established. Actual capacitance of the B43456A9228M000 is determined by the area of its metal plate, insulating oxide film and dielectric material. The oxide layer must be return to its original state before the capacitor can be reused. Thus, the electrolyte in applied filtered current must penetrate the oxide layer to restore the oxide layer.In conclusion, B43456A9228M000 are aluminum electrolytic capacitors with capacitance of 0.47µf, and a rated voltage of 25V. Their working temperature range is -55℃~105℃, and they are usually used in electronic circuits for power supply filtering, vibrator devices, resonance circuit and timing circuit. The working principle of AEC is based on the mechanism of electrolytic double layer dielectric, and the capacitance of the B43456A9228M000 is determined by the area of its metal plate, insulating oxide film and dielectric material.
