TH3B475K025E2800 Capacitors

Tantalum Capacitors

TH3B475K025E2800 is one type of tantalum capacitor. It is a form of electrolytic capacitor, which consists of two metal plates separated by a thin oxide layer that stores energy using the phenomenon of human energy. This capacitor has many excellent characteristics compared to traditional ceramic, electrolytic and film capacitors. These include low ESR, compact size, higher temperature range, longer lifetime and most notably, superior electrical stability.

Application Field

Tantalum capacitors are widely used in a variety of different applications, including automotive, medical, communications, power management, and industrial systems. Due to its low ESR, it is ideal for decoupling, filtering, and buffering purposes. The capacitor is usually used in power supplies to provide clean electrical power to the main system. It is also widely used in military applications due to its AEC-Q200 compliant leadless configuration, which reduces the chances of shorting out the electronics.

Working Principle

The TH3B475K025E2800 capacitor is based on the principle of electrochemical energy storage. The two metal plates are internally enclosed in a polymer dielectric, which has a high dielectric constant. This dielectric stores energy electrostatically, which allows the capacitor to retain its electrical parameters over time. The characteristic impedance of the capacitor and the amount of energy stored in it depend on the thickness of the dielectric. The higher the voltage applied to the capacitor, the greater the capacitance and energy stored.

Whenever a voltage is applied to the capacitor, electric charges will start to accumulate on the capacitor plates. This charge separation creates a static electric field within the dielectric, which stores electrical energy. When the voltage is removed, the charge stored in the dielectric is gradually depleted and the capacitor plate charge begins to discharge. This self-dischargeability allows the capacitor to store more energy for a longer time.

The self-discharge current is also used to detect whether the capacitor is connected in parallel with a circuit element. If the capacitor is connected in parallel, it may cause an increase in self-discharge current. This can be used to detect the presence of an open circuit element or a short circuit element in the parallel circuit.

Conclusion

TH3B475K025E2800 is an ideal choice for many applications, such as decoupling, filtering, buffering, and military applications. It is a type of tantalum capacitor that stores energy using the phenomenon of electrochemical energy storage. This capacitor provides excellent performance, stability, and long lifetime compared to traditional ceramic and film capacitors. It is also highly reliable and has a high capacity for energy storage.
