Aluminum Electrolytic Capacitors: 80ZLH470MEFCG412.5X35 Application Field and Working Principle

Aluminum electrolytic capacitors are sealed electrochemical devices composed of two aluminum foils covered with a layer of oxide film. They are divided into oil-filled and solid capacitors. The former requires lower volume and higher switch, and the latter has higher insulation resistance and leakage current than oil-filled capacitors. The 80ZLH470MEFCG412.5X35 belongs to the solid capacitor.

Application Field

Aluminum electrolytic capacitors can be used in various fields such as mobile phone chargers, digital products, medical equipment, power supply, etc. The 80ZLH470MEFCG412.5X35 is specifically designed for mobile phone chargers, for its high capacitance, stability, and long service life. It also has a variety of feature benefits, such as low equivalent series resistance, high ripple current, low temperature rise, and surge protection.

Working principle

The working principle of aluminum electrolytic capacitor is relatively simple. It is mainly composed of two metal plates (usually aluminum) and electrolyte. The aluminum foil is rolled up into an anode and the electrolyte penetrates the anode. When voltage is applied, it’s equalization of potential causes the anode and cathode to form an electrical field with the electrolyte, which separates anions and cations. These ions then give rise to the production of electrons and protons.

The electrons are the effective factor of capacitance. When the capacitor is fully charged, the electrons are released from the anode and fill the space between the cathode and anode. This creates a stored electric field between the two layers. This electric field is simultaneously discharged and recharged during field application, forming a kind of cycle. This process allows capacitors to store electrical energy.
