Working Principle

The MAL250017122E3 aluminum electrolytic capacitors use an aluminum oxide insulating layer between two metal plates. The oxide layer on the anode is very thin and is responsible for the electrical charge storage property of the capacitor. When a voltage is applied to the terminal, a reversible oxidation and reduction reactions take place which concentrate electrons in the oxide layer. This phenomenon results in charge storage for a given time.The electrical properties of the MAL250017122E3 series of capacitors are mainly determined by their aluminium oxide layer. The oxide layer provides the insulation between the plates, thus ensuring that current does not leak through the capacitor. The electrical response of the oxide layer is also responsible for the frequency response, ESR, and ripple current of the capacitor.

Conclusion

The MAL250017122E3 series of aluminum electrolytic capacitors have proven to be an effective and reliable choice for a wide range of applications. Their high thermal and mechanical stability, as well as their high frequency response, ESR, and ripple current make them a popular choice for electronic applications. Thanks to their advanced design and technology, the MAL250017122E3 capacitors ensure a high level of performance and reliability.
