Aluminum electrolytic capacitors consist of a stable anode made of pure aluminum, an electrolyte of manganese dioxide and a self-fabricated cathode foil of pure aluminum as a reaction product of the electrolyte. They are used mainly in wave-filtering, bulk energy storage and pulse-discharge applications. The EFL-100ELL470ME07D is an aluminum-electrolytic capacitor with excellent working parameters, very low ESR and increased capacitance values.

EFL-100ELL470ME07D Application Fields

The EFL-100ELL470ME07D is mainly used in AC applications, such as surge protection circuits, automotive electronics, power supplies and other power converter applications. It has a very low ESR value, which is an important parameter for any capacitive filter in AC applications.

The EFL-100ELL470ME07D can also be used in DC applications, such as telecom applications and many industrial instruments, as it has a very low leakage current and high capacitance. This makes it suitable for applications requiring very high stability and low temperature drift.

EFL-100ELL470ME07D Working Principle

The EFL-100ELL470ME07D is composed of an anode made of pure aluminum, a highly conductive electrolyte, and a self-formed cathode foil of pure aluminum. It is designed to have a very low ESR and very high capacitance values. It also has very low inductance and non-polarized construction.

In operation, the electrical charge is stored in the capacitor as a result of a redox reaction involving the transfer of electrons between the anode and cathode. The capacitance values are mainly determined by the area of the anode and cathode, the distance between them, and the properties of the electrolyte.

The polarized construction makes the capacitor suitable for AC applications. The self-formed cathode foil forms a very thin dielectric layer which prevents current from flowing between the anode and cathode. This increases the longevity of the capacitor, as the dielectric layer acts as a shield against high currents in the event of an overvoltage situation.

Conclusion

The EFL-100ELL470ME07D is an aluminum electrolytic capacitor with excellent parameters, very low ESR and increased capacitance values. It is suitable for use in both AC and DC applications due to its non-polarized construction and very low leakage current. The redox reaction at its core enables it to store charge, and its polarized construction makes it suitable for AC applications. With these features and its exceptional parameters, the EFL-100ELL470ME07D makes an excellent choice for any application requiring an aluminum electrolytic capacitor.
