Tantalum capacitors are a type of electrolytic capacitor, the oxide of which serves as the dielectric material. They are the most popular replacement for aluminum electrolytic capacitors because of their advantages in terms of their smaller size and greater temperature stability. The THJB105M035RJN, as a kind of tantalum capacitor, is widely used in high power automotive and industrial control applications, and also in consumer electronics.

Working Principle

Tantalum capacitors are categorized as polarized capacitors due to their construction and electrical properties. Inside the capacitor, two conductive plates are separated by a dielectric layer that is made of tantalum pentoxide (Ta₂O₅). The dielectric layer, along with the cathode (negative) terminal, can store electrical charges, enabling it to act as a capacitor.

The electrode plates are made out of a sintered pellet of tantalum powder, which is placed in an anode (positive) terminal made of an electrically conductive material such as manganese dioxide, niobium pentoxide, carbon, or polytetrafluoroethylene. When a voltage is applied to the terminals of the capacitor, the charge is stored in the dielectric layer between the two plates.

When the applied voltage is removed, the charge remains stored in the capacitor, ready to be transferred upon reapplication of the voltage. The stored energy within the capacitor is related to the dielectric\'s energy constant and the capacitance of the device. The rate of charge transfer is also affected by the capacitance of the capacitor.
