Tantalum capacitors characteristic

Tantalum capacitors can easily obtain large capacitance, and have few competitors in power filter, AC bypass, and other applications; It has a single conductivity, known as "polarity". When applying, current should be connected in the positive and negative directions of the power supply. The anode (positive electrode) of the capacitor should be connected to the "+" electrode of the power supply, and the cathode (negative electrode) should be connected to the "-" electrode of the power supply. "If the capacitor is incorrectly connected, it will not only fail to function, but also have a large leakage current. In a short time, the core will generate heat, damage the oxide film, and then fail, causing adverse consequences.". [4]

The operating voltage of tantalum capacitors has a certain upper limit, but this disadvantage is not important for matching transistors or integrated circuit power supplies.

Tantalum capacitors have the performance of storing electricity, charging and discharging
