Aluminum electrolytic capacitors are a type of electrolytic capacitors. They have large capacitance and are widely used in various electronic circuits. The characteristic parameters of aluminum electrolytic capacitors include series number, capacitance, rated voltage, equivalent series resistance (ESR) and surge capability. 420BXW68MEFR12.5X45 is a type of aluminum electrolytic capacitor. In this article, the application field and working principle of 420BXW68MEFR12.5X45 is discussed.

Application Field of 420BXW68MEFR12.5X45

Aluminum electrolytic capacitors are often used in power supplies, decoupling filters, stabilization, and similar applications. 420BXW68MEFR12.5X45 is a type of aluminum electrolytic capacitor produced by HEC (Henan Electronic Component). It has a maximum operating temperature of +105 °C, rated voltage of 450 V, and capacitance of 68 μF, and thus it is suitable for industrial and commercial applications. It is often used in loudspeakers, switching power supplies, LED lighting and high power rectifiers. 420BXW68MEFR12.5X45 is also used in automotive applications such as assembly components in hybrid and electric vehicles.

Working Principle of 420BXW68MEFR12.5X45

Aluminum electrolytic capacitors consist of two metal plates separated by an electrolyte, which is typically an aqueous solution. The plates are the anode and the cathode, and the electrolyte serves to keep them apart. When a voltage is applied to the capacitor, the anode receives electrons from the voltage source, while the cathode releases electrons into the electrolyte. This generates an electric field across the capacitor, which is then converted into a charge on the electrodes. The anode can carry more positive charge than the cathode, and thus it generates a greater electrical field between the two electrodes. The charge on the anode is greater than the charge on the cathode, and thus it creates a polarized field surrounding the capacitor.

420BXW68MEFR12.5X45 is a type of polarized aluminum electrolytic capacitor. It has a maximum operating temperature of +105 °C, rated voltage of 450 V, and capacitance of 68 μF. It consists of a cathode foil coated with an aluminum oxide film along with dielectric insulators. The negative terminal of the capacitor is usually identified by a "+" sign. The can is filled with a liquid electrolyte that is usually a combination of organic solvents and acids.

The working of 420BXW68MEFR12.5X45 is based on the same principle. When voltage is applied, electrons flow from the anode to the cathode, and the electric field between them increases to create a charge separation. The electric field creates both capacitive and inductive elements in the circuit. The former is responsible for storing energy while the latter produces a voltage across the terminals as the current changes. This allows 420BXW68MEFR12.5X45 to act as an electrical and mechanical energy storage device.

Conclusion

420BXW68MEFR12.5X45 is a type of aluminum electrolytic capacitor. It has a maximum operating temperature of +105 °C, rated voltage of 450 V, and capacitance of 68 μF. It is used in a variety of applications such as loudspeakers, automotive components, and power supplies. The working of 420BXW68MEFR12.5X45 is based on the same principle as other aluminum electrolytic capacitors. When voltage is applied, electrons flow from the anode to the cathode, and the electric field between them increases to create a charge separation. This allows 420BXW68MEFR12.5X45 to act as an electrical and mechanical energy storage device.
