EEE-FK1E122SQ

Aluminum electrolytic capacitors are a type of non-polarized electrolytic capacitors whose anode is composed of an electrolyte and an aluminum oxide film, and a metal shell serving as the cathode. The EEE-FK1E122SQ application field and working principle belonging to aluminum electrolytic capacitors are introduced in this article.

EEE-FK1E122SQ is a miniature, low-profile, low-ESR plug-in aluminum electrolytic capacitor and has a wide range of applications. It focuses on the fields of power switchgear, electric power, household appliances, automotive vehicles and various portable electronic devices. Taking into account the characteristics of small size, high voltage, long life and low leakage current, the product is suitable for equipment with GB 1276, GB 14048.1, GB 15922.2 standards.

The EEE-FK1E122SQ is a long life plug-in aluminum electrolytic capacitor that works by utilizing the alloy of aluminum electrodes and electrolyte. The aluminum oxide dielectric formed on the aluminum foil surface functions as an electric field and charge storage layer. The radiation part of the electric field is very large and is the main reason for the high capacitance. The space part is generally very small and is used as an insulation layer. When voltage is applied, a large amount of electricity passes through the oxide layer, and a current flows through the aluminum foil. This current causes self-heating and evaporation of the electrolyte. After evaporation, the electrolyte is sprayed onto the entire plane of the aluminum foil, and the film grows thicker.

The EEE-FK1E122SQ has a miniature, low-profile, low ESR and long life features. The nickel-plated brass top cover and spiral slot ensures a smaller size and the use of conductive polymer aluminum solid electrolyte (POSCAP)(TM) technology ensures a longer life. The low ESR ensures stable and ripple absorption of ripple current, and the entire series meets AEC-Q200 automotive electronic quality standard.

In conclusion, the EEE-FK1E122SQ application field includes power switchgear, electric power, household appliances, automotive vehicles and various portable electronic devices. Its working principle is based on the electrochemical action of aluminum alloy and electrolyte, forming a dielectric aluminum oxide film, and aluminum current flows through the film to cause self-heating and electrolyte evaporation.
