MAL209453271E3 Datasheet/PDFAluminum Electrolytic Capacitors
Aluminum electrolytic capacitors (AECs) are a type of capacitor that uses a wet electrolyte type electric double layer capacitor formed between a pair of aluminum foil electrodes with a surface oxide film as a capacitor dielectric. MAL209453271E3 is a type of aluminum electrolytic capacitor, which used in a variety of applications and has different specific functions based on its working principle.
Application Field
MAL209453271E3 applies to pulse power supply units on general-purpose automotive engine controllers, car audio systems and rear view monitors. The features of this product are low impedance, long life and high ripple current. It can be used in a variety of harsh environments including high temperature, high vibration and high humidity.
Working Principle
The main function of MAL209453271E3 is to store and release energy. It uses a wet electrolyte capacitor to generate an electric double layer at the interface between the two aluminum foils, with the dielectric being a thin oxide film. The oxide film is formed through anodization of the two surfaces of the aluminum foil, so that the surface area of the dielectric layer is maximized and the internal resistance of the capacitor is reduced, enabling it to withstand a high energy density.
In terms of storage and release, due to the equivalent capacitance of the wet electrolyte capacitor, after the capacitor is charged, the energy will be constantly released. Under the driving of the voltage, electrons flow until they reach the other end of the capacitor. The charge is then stored in the capacitor until the voltage is released, at which point the process reverses and the electrons are released from the capacitor.
Conclusion
In conclusion, MAL209453271E3 is an aluminum electrolytic capacitor used for pulse power supplies on general-purpose automotive engine controllers, car audio systems, and rear view monitors. It adopts the principle of wet electrolyte capacitance and is characterized by low impedance, long life and high ripple current.
