Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, with a layer of tantalum pentoxide as an electrolyte. They have a high capacitance, small size, and long service life, making them ideal for a variety of applications. The TR3B156M010C0700 is a common tantalum capacitor, and is used in consumer electronics and automotive systems.

Application Field

Tantalum capacitors are commonly used in consumer electronics as de-coupling capacitors on power supplies. They are also used in parallel with electrolytic capacitors in signal filtering applications. Tantalum capacitors are often found in radio communication systems and digital signal processing circuitry due to their noise suppression capabilities. Finally, they are also used for voltage-regulation in automotive engines and other industrial applications.

Working Principle

Tantalum capacitors are basically comprised of two electrodes, a tantalum anode, and a cathode. The anode is formed into a highly porous structure, and the electrolyte, which consists of tantalum pentoxide, is absorbed into the anode\'s pores. This forms a dielectric barrier between the two electrodes. When a voltage is applied across the two electrodes, the capacitor allows electric current to flow between them due to the presence of the tantalum pentoxide electrolyte.

The advantages of tantalum capacitors, relative to other types of capacitors, include their relatively high capacitance and low ESR (Equivalent Series Resistance). The combination of these two characteristics yields a linear and consistent relationship between the voltage and the current, which makes them suitable for a wide range of applications. In addition, their long life expectancy, ability to operate at high temperatures, and small size make them particularly attractive for automotive, aircraft, and other industrial applications.
