Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are components used to store electrical energy or to act as a receiver or transmitter of alternating electrical current. Specifically, they are polarized aluminum capacitors with a dielectric oxide layer on the anode and electrolyte as the cathode. It has the advantages of large capacity, high operating voltage, small size, light weight and high cost performance.

B43510A0188M000 application field and working principle

• Application Field: B43510A0188M000 Aluminum electrolytic capacitors are widely used in OA (such as copiers, printers), AV (such as TV, DVD, CD), communication (such as cellular phones, facsimile machines), home electric appliances, control equipment and so on.
• Working Principle: Aluminum electrolytic capacitors are passive components composed of an aluminum foil (including a solid or osmium film) used as the anode, a dielectric oxide layer corresponding to the oxide film electrode used as the cathode, an insulating layer and an electrolyte. When applying a working voltage, the electric field generated by the capacitor will allow electrons to flow from the aluminum foil to the aluminum oxide layer on the cathode, thus forming a capacitor. At the same time, the electrolyte (film can) participates in charging and discharging, resulting in the formation of an electric double layer.

Every type of aluminum electrolytic capacitor has its own unique advantages and disadvantages. B43510A0188M000 aluminum electrolytic capacitors are mainly used in large-capacity and small-sized electronic equipment, which are of great significance for miniaturization and lightening of electronic equipment.
