タイトルまたは説明

Electrolytic capacitor is usually composed of metal foil (aluminum/tantalum) as a positive electrode, foil the insulating oxide layer (alumina/tantalum pentoxide) as the dielectric, electrolytic capacitor with its positive electrode divided into aluminum electrolytic capacitor and tantalum electrolytic capacitor. The negative electrode of aluminum electrolytic capacitors by soaked in electrolyte fluid (liquid electrolyte) tissue paper/film or polymer electrolyte composition; Manganese dioxide tantalum electrolytic capacitor negative electrode is usually adopted. 

Application:

Application of polar electrolytic capacitor is usually in the power supply circuit or intermediate frequency and low frequency circuit power filtering, decoupling, such as signal coupling and time constant is set, the dc insulation effect. Generally cannot be used for the ac power circuit, the dc power supply circuit for the use of filter capacitance, the anode (the anode) should be connected with the positive facies of the power supply voltage, cathode negative electrode (cathode) and the power supply voltage at the connection, not against
