The working principle of the381EL122M200A042 is 1 based on the characteristic of an electrolytic capacitor, a type of capacitor which operates through the use of two aluminium plates separated by an electrolyte material. When a steady DC electrical potential is applied to the device, an electric field or Faraday cage forms around the two plates, resulting in a dielectric material being formed near the negative plate and a porous oxide coating creating a higher resistance on the positive plate. This reduces the flow of electric charge, creating a higher voltage at the positive side of the capacitor than the negative side. The resulting voltage difference created by the physical separation of the two plates, along with the electric field formed between them, allows the capacitor to store and release electrical energy at a later time.

Overall,381EL122M200A042 can be categorised as an aluminum electrolytic capacitor. It boasts an impressive capacitance rating of 1.2µF, a robust working voltage of 200V and low equivalent series resistance. It is a useful part for a wide range of applications, especially those requiring high voltage regulators, power converters and power supply output filter circuits due to its high ripple current rating, wide temperature range and large capacitance.
