Working Principle

An electrolytic capacitor basically comprises of two metallic plates that are wrapped by two conductive layers of an electrolyte-soaked paper and then sealed in a can. The capacitor leverages a chemical reaction that causes oxygen ions to be chemically absorbed on the capacitor\'s anode plate, forming a thin insulating barrier known as the oxide layer at the electrode surface. The ions then transfer from one plate to the other to create a separation of electrical charge.

The aluminum electrolytic capacitors perform with much larger capacitance than film capacitors, thanks to a large surface area of anode material as well as a substantial distance between the two electrodes. Besides, their paper separator that contains the electrolyte solution also serves as an internal dielectric, improving significantly capacitance values.

The great performance of PEH200ZO418HMBA results from that its anode is constructed with a unique high purity cathode aluminum and an electrolyte material which presents superior endurance. Additionally, PEH200ZO418HMBA is also equipped with a special voltage endurance test and long life to ensure a dependable performance.
