Tantalum Capacitors

Tantalum capacitors are one of the most commonly used electronic components. They are widely used in a variety of applications, and are known for their high reliability, long life, small size, and low leakage current compared to other capacitor types. The TAP156M016CCS (17 x 10mm, 10V SMD tantalum capacitor) is one of the most widely available of these components. This article will discuss the application field and working principle of the TAP156M016CCS.

Application Field of the TAP156M016CCS

The TAP156M016CCS is a 10V SMD tantalum capacitor, which is primarily used in low-voltage, high-density circuit designs. Common applications include: power supplies, decoupling, signal conditioning, and back-up and battery charging circuits. The small size and low-leakage current capability of the TAP156M016CCS make it an ideal choice for use in portable and handheld devices such as cell phones and tablets, where board space is limited.

Working Principle of the TAP156M016CCS

Tantalum capacitors work on the principle of electrochemical capacitance. Electrochemical capacitance occurs when a thin layer of oxide forms on the surface of a tantalum wire, resulting in a parallel-plate capacitor. This oxide layer acts as the dielectric material and is capable of storing charge. The capacitor is then charged and discharged through a pair of electrodes.

When charging the capacitor, current passes through the oxide layer, depositing an electrode of positive ions on the oxide surface. As the oxide layer thickens, its resistance increases, limiting the amount of current that can pass through the oxide layer. Once the maximum charge level has been reached, the capacitor is said to be “saturated” and no more current can be passed through the oxide layer.

Discharging the capacitor works in reverse. As the current passes through the oxide layer, the ions remove the positive ions from the oxide surface, resulting in a decrease of the capacitor’s charge. When the charge level has reached zero, the capacitor is said to be “empty” and no more current can be passed through the oxide layer.

Conclusion

TAP156M016CCS is a 10V SMD tantalum capacitor that is used in a variety of applications due to its small size and low leakage current. Its working principle is based on the principle of electrochemical capacitance. By understanding the application field and working principle of the TAP156M016CCS, one can make better-informed decisions when selecting the right capacitor for the job.
