Aluminum electrolytic capacitors consists of two aluminum plates spaced apart so that the electric field is concentrated between the plates. The anode and cathode of the capacitor are separated by a layer of electrolyte, usually a type of liquid that conducts electricity. When a voltage is applied to the capacitor, the inner surfaces of the two plates become positively or negatively charged, depending on the direction of the current. This creates an electrostatic attraction between the two plates, causing a layer of electrolyte to form between them.

E81D401VND821MA60N aluminum electrolytic capacitors is suitable for mounting on printed circuit boards with high resistance to humidity in combination of a long life and enhanced electrical reliability, and feature:

  • Rated voltage: 200V
  • Capacitance: 800μF
  • Withstand Voltage: 275V AC, 5 sec.
  • Leakage current: 2.5mA max.
  • Temperature Range: -40 ~ +105℃
  • Lead Plating: Sn over Ni

The application field of aluminium electrolytic capacitors is vast and varied. They are widely used in the energy supply indudstry, consumer electronics, automotive industry and other specialized applications. E81D401VND821MA60N is a kind of very large capacity aluminum electrolytic capacitors, so it can be used in very large capacity DC power supply, motor drive and similar fields.

In terms of working principle, E81D401VND821MA60N aluminum electrolytic capacitors utilizes a thin oxide layer that forms between two aluminum plates when a voltage is applied. This layer increases the capacitance of the capacitor and acts as an electrical insulator, preventing current from flowing directly between the plates. When the voltage applied to the plates is greater than the rated voltage, the capacitor will start to discharge through the oxide layer, creating a "capacitor bleed" phenomenon. The amount of current it can support in this "bleed" state depends on the amount of oxide that has formed between the two plates of the capacitor.

This type of capacitor also has a self-discharge property, also known as dielectric absorption or dissipation. The capacitance value of these capacitors decreases over time as the oxide layer slowly charges up with electrons. This process of self-discharge occurs slowly over time until the oxide layer has been completely re-formed.

E81D401VND821MA60N aluminum electrolytic capacitors are widely used in low-frequency switching power supplies, inverter power supplies, DC and AC motor inverters, and UPS power supplies, because they can store and release large amounts of energy quickly, feature high-frequency response, and offer good long-term reliability.
