Working Principle of T495X107K020ATE150

The T495X107K020ATE150 operates as a solid tantalum capacitor, which is based on the principle of charge storage between two conductive plates separated by a dielectric. Here's how it works:

Construction:

• The anode is made of tantalum metal, which is shaped into a porous structure to maximize surface area.
• A thin layer of tantalum pentoxide (Ta₂O₅) forms on the surface of the anode, acting as the dielectric.
• A conductive cathode is made of a solid electrolyte, typically manganese dioxide (MnO₂), that covers the dielectric.

Charge Storage:

• When a voltage is applied, positive charges accumulate on the anode, and negative charges accumulate on the cathode. The tantalum pentoxide dielectric layer blocks the flow of direct current (DC) while allowing the capacitor to store energy in the electric field between the anode and cathode.

Polarization:

• Tantalum capacitors are polarized, meaning they must be connected with the correct polarity—positive to the anode and negative to the cathode—otherwise, they could fail or short-circuit.

Discharge:

• When the circuit requires energy, the stored charge is released, allowing the capacitor to smooth voltage fluctuations, filter noise, or provide power for short durations.

Low ESR:

• The solid electrolyte provides low equivalent series resistance (ESR), enabling the capacitor to handle high-frequency signals and rapid charging/discharging cycles, making it ideal for power supplies and decoupling applications.
