Aluminum Electrolytic Capacitors

Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized aluminum capacitors whose anode is made of aluminum foil with oxide film formed on its surface. Together with the electrolyte, it forms an anode/electrolyte/a layer of porous film. It is called solid electrolyte capacitor, which can store electric energy. It is mainly used for current filtering, noise suppression, AC-DC rectification and frequency compensation in the circuit.

Application and Working Principle of UKL1J680KPD

The application field of UKL1J680KPD is mainly for signal noise filter, frequency compensation and DC/AC rectification circuit in TV, etc. UKL1J680KPD is a type of aluminum electrolytic capacitors. Working principle of UKL1J680KPD is similar to that of aluminum electrolytic capacitors. Its essential components are made of aluminum foil, an electrolyte and a section of porous ceramic split-type. The electrode of capacitor is electrolyte soaked paper, which directly contacts both electrodes. Under the effect of electric field, the oxide film is quickly formed on the aluminum foil surface to produce an insulating layer, so as to reduce the leakage current.

Advantages and Disadvantages of UKL1J680KPD

Advantages of UKL1J680KPD include small size, light weight, low cost and wide capacity range. The maximum rated capacity of UKL1J680KPD is 680uF and the working voltage range is 6.3V-50V. In addition, its unique characteristics can effectively filter electronic noise, reduce interference and enhance system stability.

However, the disadvantage of UKL1J680KPD is that its voltage can only be applied in one direction. The working temperature range of UKL1J680KPD is limited, and its temperature coefficient has great impact on the parameters of capacitance, equivalent series resistance, insulation resistance and other properties. In addition, its load life time is relatively short. Therefore, application of UKL1J680KPD should be carefully selected on the basis of actual parameters.

Conclusion

UKL1J680KPD is a type of aluminum electrolytic capacitor with small size, light weight, low cost and wide capacity range. Compared with other electrolytic capacitors, it has the characteristics of low cost, large capacity, low leakage current and high stability. The application field of UKL1J680KPD is mainly for noise filter, frequency compensation and DC/AC rectification circuit in TV, etc. However, UKL1J680KPD has the potential disadvantages such as voltage applies only in one direction, limited working temperature range and limited load life time.
