Aluminum electrolytic capacitors (commonly known as electrolytic capacitors) are made of aluminum foil and insulating paper. The capacitor uses an electrolyte (electrolyte) to wet the plate on the aluminum foil. The electrolyte is an ion exchange medium that enables a certain amount of ions to transfer between the two plates. By regulating the amount of ions on the two plates, the capacitance of the electrolytic capacitor can be changed and the voltage of the aluminum foil can be stabilized. This 16YK2200MEFC12.5X20 belongs to the aluminum electrolytic capacitor

Use: 16YK2200MEFC12.5X20 Aluminum electrolytic capacitors are widely used in power conversions, inverters, audio, DC-DC, temperature control, control circuit, switch, LED screen and so on. Due to their robustness, safety, reliability and low equivalent series resistance (ESR), aluminum electrolytic capacitors are the preferred capacitance for power hard switching designs. (Examples: high switch limit inductive loads such as DC-DC converters and air conditioners, fridge motors, etc)

Working Principle: The working principle of the 16YK2200MEFC12.5X20 aluminum electrolytic capacitor is electrostatic. A plate on the anode (aluminum foil) is deposited with an oxide layer, and the anode and the cathode are separated by the oxide layer. When a voltage is applied, a dielectric between the plates causes the capacitor to store charge. When the voltage is removed, the electric charge on the plate will dissipate, but it will take a longer time to do so. This is because the oxide layer helps to maintain the charge after voltage removal. In addition, the dielectric layer helps to reduce the leakage current.

Structure: The 16YK2200MEFC12.5X20 aluminum electrolytic capacitor consists of terminals, base, dielectric, aluminum foil, sealant, and internal pressure release device. Theterminal is clad with an aluminum shell, the base is made of plastic to insulate the capacitor body, the dielectric is a film made of polyethylene, the aluminum foil is placed axially on the center of the surface, and the sealant is an insulating material that seals the edges of the capacitors. The internal pressure release device is a layer that allows excess gas to escape through a small hole.

Compared to other capacitors, the 16YK2200MEFC12.5X20 aluminum electrolytic capacitor is relatively easy to recharge, its self-healing nature allows it to recover from a fault, and it is cost-effective and has a wide capacitance range. Moreover, aluminum electrolytic capacitors have the ability to withstand high current surges and high voltage spikes. However, they are not suitable for use in high frequency circuits and are prone to failure under severe operating conditions.

In conclusion, 16YK2200MEFC12.5X20 aluminum electrolytic capacitors are widely used in a variety of applications and are valued for their robustness, safety, and reliability. Their low equivalent series resistance and wide capacitance range make them ideal for use in power conversion and inverter designs.
