• Aluminum Electrolytic Capacitors
• ECA-1HM010I application field and working principle
• Introduction
  • Aluminum electrolytic capacitors are a type of electrolytic capacitor that uses an aluminum oxide film as the cathode dielectric. It is an electrolytic capacitor with a larger capacitance per unit volume, which has the advantages of high energy density, high capacitance value, long life and low temperature coefficient.
• Application Field
  • ECA-1HM010I aluminum electrolytic capacitors are widely used in the fields of power electronic components, LED lighting, instrumentation, industrial control, automotive electronics, smart grid, etc.
• Working Principle
  • The working principle of ECA-1HM010I aluminum electrolytic capacitor can easily be understood. Firstly, the dielectric is an aluminum oxide film, which is formed by anodizing the aluminum foil. A capacitive electrode is formed on each side of the oxide film, and electrolyte is placed in the device. When an alternating voltage is applied, the oxide film will cause a current leakage from the negative terminal to the positive terminal.
  • Under the action of the electric field, the oxidation and reduction reactions will occur in the electrolyte. The electric field will accelerate this reaction rate, causing charge transfer or charge accumulation. This charge accumulation will produce a capacitance between two electrodes. The frequency characteristics of the capacitor can be changed by changing the relative permittivity of the dielectric.
