For example, it is used in the defense and aerospace industry, including military aircraft, space vehicles, and satellites, where it is expected to withstand high shock, vibration, and temperature changes. It is also used in surface and underground mining vehicles and submarines, where it often confronts extreme temperature and wetness conditions.In addition to these applications, the TR3B156K020C1000 is also widely used in the automotive and medical industries. The automotive industry often makes use of its superb electric properties, while medical applications can benefit from its robust and reliable performance, as well as its total absence of electrolyte leakage.

Working Principle

The working principle of a tantalum capacitor is very simple. It consists of two electrodes (anode and cathode) separated by an insulator (dielectric) and an electrolyte. When a voltage is applied to the two electrodes, electric charge accumulates at the surface of the dielectric, creating an electric field. This electric field will create an electric charge of opposite polarity on both sides of the dielectric. Since the accumulation of charges creates a barrier to current flow, the capacitor will act as a filter and be able to store energy.The TR3B156K020C1000 utilizes a tantalum pentoxide (Ta2O5) dielectric and a porous anode, which ensures it is capable of handling high capacitance and high frequencies. Its use of a manganese dioxide electrolyte offers outstanding reliability, even in the most hostile environments.

Conclusion

The TR3B156K020C1000 is a high-performance tantalum capacitor that is suitable for extreme applications. Its features, such as its robustness, high peak-load current, low ESR, and resistance to temperature changes, make it a suitable choice for extreme military, aerospace, automotive and medical industries. The working principle of the TR3B156K020C1000 is based on electric charge accumulation creating a barrier to current flow and storing energy as a result.
