13008-053KESA Application Field and Working Principle of Tantalum Capacitors

Tantalum capacitors are tantalum oxide-based capacitors in the form of tiny metallic components that are used in various types of electronic systems. They consist of two electrodes that are connected by either an electrolytic paste or a gel, creating a total capacitance. A tantalum capacitor is generally more reliable than other types of capacitors because it is resistant to corrosion and offers excellent thermal and temperature performance.

Application Field

Tantalum capacitors are generally used in applications requiring a large amount of capacitance such as power supplies, radio frequency (RF) circuits, and audio amplifiers. They are also used in computer systems, communication systems, motor drive controllers, industrial and medical equipment, and semiconductor applications. In power supplies, tantalum capacitors are used to store energy, allowing a power supply to rapidly deliver power to devices such as digital clocks. They are also essential to frequency-tuned circuits, as they are stable over a range of frequencies and temperatures. Tantalum capacitors offer improved performance, efficiency, and reliability over other types of capacitors in motor drive controllers and digital signal processing (DSP) systems. In computer systems, tantalum capacitors provide low-leakage performance and are used for decoupling and power supply bypassing, and are essential for memory controllers and data handlers. They also have excellent performance in RF circuits, and are able to provide stable power for signal amplifiers and oscillators with higher resonance stability. In addition, they are used to help reduce the use of inductors in high-frequency circuits.

Working Principle

The working principle of a tantalum capacitor is based on the process of electrolytic oxidation-reduction. At the anode electrode, the chemical reduction reaction produces a film of oxidation with the surface material. This oxide film acts like a dielectric medium, creating an electrical field between the two electrodes. The electrical field allows electrical current to pass between the electrodes and charges the capacitor. When the capacitor is connected in a circuit, it creates a charge. The size of the circuit will determine the amount of charge storage and the capacitance value of the capacitor. When the capacitor is discharged, the charge will flow along the circuit until it reaches equilibrium.Additionally, tantalum capacitors are designed with a protection circuit, which is a current-limiting mechanism. This protects the capacitor by limiting the current that flows into or out of the capacitor. This helps to prevent damage to the capacitor or other components in the circuit. In summary, tantalum capacitors provide an effective solution for various applications due to their ability to store small amounts of power, their stability over temperature and frequency, and their excellent corrosion resistance. They are a reliable and efficient way to support critical power supply circuits, and also provide low leakage voltage performance for computer systems, communication systems, and more.
