Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are an essential component of power supplies, power conversion, and other power systems in many different industries. AECs offer a large capacitance value for a small physical package and can provide efficient power delivery for long periods of time with minimal energy losses. The 400TXW47MEFC12.5X30 is a specific type of AEC and they are typically used in the following applications:

Application Field

The 400TXW47MEFC12.5X30 aluminum electrolytic capacitor is designed primarily for high voltage, high capacitance applications in both consumer and industrial electronics. Specifically, it is suitable for use in automobiles, telecommunications equipment, and other high-power systems which require reliable energy storage and delivery. It is also common to find the 400TXW47MEFC12.5X30 in medical and military applications as it offers superior capacitance-voltage characteristics and is capable of withstanding high temperatures.

Working Principle

The 400TXW47MEFC12.5X30 aluminum electrolytic capacitor consists of an anode and a cathode layer separated by an electrolyte. The anode comprises of a thin layer of oxide-coated aluminum foil and the cathode a non-conducting film. As the electric current flows through the anode and cathode layers, a chemical reaction takes place between the electrolyte and the metal foil. This chemical reaction produces electric charge and charges up the capacitor. When the power supply is switched off, the electric charge stored in the capacitor gets discharged until it is completely discharged.The capacitance and voltage ratings of the 400TXW47MEFC12.5X30 aluminum electrolytic capacitor depend on the thickness of the oxide film and the type of electrolyte used. Generally, the thicker the oxide film, the higher the capacitance and voltage ratings of the capacitor. Furthermore, the electrolyte used in these capacitors has dielectric properties which further enhance the capacitance and voltage ratings.

Conclusion

In conclusion, the 400TXW47MEFC12.5X30 aluminum electrolytic capacitor is designed to provide reliable energy storage and delivery to a wide range of high-power applications. Its ability to withstand high temperatures and voltage ranges make it a popular choice for military and medical applications. Furthermore, its capacitance-voltage characteristic ensures efficient power delivery for long periods of time with minimal energy losses.
