Tantalum Capacitors

Tantalum capacitors are an essential component of any electronics, and one of the most commonly used type of capacitors. The “Tantalum” part of the name refers to the material used in the construction of the capacitor and the “Capacitor” part refers to the ability to store electric charge. This article will detail the application field and working principle of the type of capacitor referred to as the TPSB225K035R2000.

Application Field

The TPSB225K035R2000 tantalum capacitor is designed for both military and commercial electronic applications and it is highly reliable and long-lasting even under diverse application conditions. The capacitor is a high frequency, low signal, polarised miniature type, suitable for circuit board mounting and is made from first-class plastics and tantalum material. It has a voltage rating of 200 volts and a capacitance range from 4.7μF to 22μF.The capacitor has a wide application in the development of current limiting circuits and short circuit protection, in frequency filters, decoupling circuits, voltage regulators and power management systems, in switching power supplies, in car audio systems and radio frequency applications, and more.

Working Principle

The TPSB225K035R2000 capacitor operates by storing and releasing energy. Its basic structure consists of two electrodes: positively charged anode and negatively charged cathode, which are separated by a dielectric. During the operation of the capacitor, charge flows from the anode to the cathode. The total amount of charge stored is determined by the voltage applied to the tantalum capacitor.The dielectric of a tantalum capacitor is generally a solid electrolyte, usually potassium tantalate equivalent. During the operation of the capacitor, the anode (positive charge) is conductive, while the cathode (negative charge) is resistive. As a result, a small resistive path is formed between the anode and the cathode, referred to as the ‘depolarization’ of the capacitor. This is the mechanism that enables the capacitor to store and release energy.

Conclusion

The TPSB225K035R2000 tantalum capacitor is an important component in a wide range of electronics applications, and its working principle essentially consists of storing electric charge in an electrochemical form. The capacitor stores electric charge until it reaches its maximum capacitance, at which point it releases the energy in the form of electricity. This type of capacitor is highly reliable and long-lasting, and it is often used in military and commercial electronics.
