Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most common types of capacitors used in the world today. They are made up of two aluminum foils in a metal cylinder filled with an electrolyte paste. The two foils act as plates with one connected to the negative terminal and the other connected to the positive terminal. The electrolyte acts as a dielectric material to store charge and increase the capacitance of the device. In aluminum electrolytic capacitors, the electrodes are typically made of aluminum and the electrolyte solution is usually an organic solvent such as ethylene glycol or ethanol.

36DY561F200AA2A Application Field and Working Principle

The 36DY561F200AA2A aluminum electrolytic capacitors are designed for use in applications where a low ESR (Equivalent Series Resistance) and a high ripple current are required. The device is a long-life, three-terminal capacitor. It has a nominal capacitance of 560µF and a maximum ripple current of 70% of the rated value of the capacitance. The 36DY561F200AA2A capacitors are used in applications such as computer motherboards, UPS, AC power supplies, etc.

The working principle of an aluminum electrolytic capacitor is based on the fact that it is made of two aluminium plates with an electrolyte paste in between. When a voltage is applied across the capacitor, a current will flow through the electrolyte which causes ions to form on the aluminium plates. This forms an electrical double layer which stores the charge and increases the capacitance of the device. As the capacitance increases, the ESR value of the capacitor decreases. The capacitance and ESR values of the 36DY561F200AA2A are rated at 560µF and 0.13Ω respectively.

In addition to the applications mentioned above, aluminum electrolytic capacitors are also used in audio systems, timers, frequency converters, DC-DC, converters, energy storage applications, digital control systems, automotive applications and lighting applications.

The 36DY561F200AA2A aluminum electrolytic capacitor is a highly reliable device with a long service life. It offers excellent frequency characteristics, low ESR, low leakage current and a high ripple current rating. The device is also RoHS compliant, making it a great choice for applications where a low ESR and a high ripple current are required.
