Working Principle

25PK470MEFCT78X11.5 tantalum capacitors utilize an electrochemical process to store energy. The two electrodes of the capacitor consist of a conductive plate and a porous anode. An electrolytic solution is used to connect the two electrodes.When a voltage is applied to the capacitor, the electrodes become polarized and current flows into the anode. This causes oxygen ions to be released from the electrolytic solution which form an oxide surface layer on the anode. As the electric current flows into the capacitor, more oxygens ions are released and the oxide layer continues to grow.The oxide layer acts as a dielectric, allowing electrons to move across the plate and store electrical charge. The oxide dielectric layer protects the anode from any damage and ensures that the stored charge is safely and securely contained. The amount of charge that can be stored in the capacitor is dependant on the surface area of the anode and the concentration of the electrolytic solution.

Conclusion

25PK470MEFCT78X11.5 capacitors are a type of aluminum electrolytic capacitor that is commonly used in applications such as industrial, automotive, telecommunications, and consumer electronics. The capacitor utilizes an electrochemical process to store electrical charge between its two electrodes, a conductive plate and a porous anode. A layer of oxides formed by the electrolytic solution acts as a dielectric between the two electrodes and allows the capacitor to safely and securely contain the stored charge.
