Tantalum Capacitors

TPSD227K010Y0150 Application Field and Working Principle

Tantalum capacitors, or tantalum electrolytic capacitors, are electrochemical capacitors (also known as an electrical double layer capacitors) that are composed of tantalum powder and are composed of two layers of metal oxide films with a tantalum anode and an electrolyte containing an oxidizing agent. As an electrode material, tantalum has many advantages, such as good chemical stability, high electrical conductivity, low dielectric loss and so on. Because of its outstanding features and good performance, tantalum capacitors have been widely used in consumer electronics and military electronics.

The main application area of TPSD227K010Y0150 is consumer electronics and military electronics. It can be used as a discreet capacitor or as a large value capacitor in microcircuits.

Working Principle of TPSD227K010Y0150

The working principle of TPSD227K010Y0150 is similar to that of other electrolytic capacitors. The capacitance and electrical properties of a tantalum capacitor is determined by two separate layers of metal oxide films. The anode layer of a tantalum electrolytic capacitor typically consists of an oxide of tantalum with a high dielectric constant. The cathode film is formed by the electrolyte containing an oxidizing agent such as potassium hydroxide. The cathode is in one way, positively charged at two different set of voltages.

When a voltage is applied to a tantalum capacitor, a steady flow of electrons passes through the capacitor generating an electric field and a flow of electric current. The electric current induces an electric field inside the dielectric. The electric field balances the electric charge on the capacitor that stores the electric energy. The higher the voltage applied to the capacitor, the greater the electric field, and the higher the electric charge stored on the capacitor.

When different set of voltages are applied to the capacitor, the electric charge stored in the capacitor changes, thus changing the electric field. It is this change in electric field that determines the capacitance of the capacitor. The higher the electric field, the lower the capacitance and the smaller the capacitor.

Conclusion

TPSD227K010Y0150 is a type of tantalum capacitor used in consumer electronics and military electronics. Its working principle is similar to other electrolytic capacitors, i.e. the higher the applied voltage, the higher the electric field and the greater the electric charge stored on the capacitor, thus determining the capacitance.
