Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are electronic capacitors that have a tantalum anode protected by a thin oxide layer created and maintained by a DC polarization process. They have the highest volumetric efficiency among all practical capacitors, and thus have become an essential component in nearly all electronics. The most common type of tantalum capacitor is a solid electrolytic device, which is marked with a part code such as 199D395X9035C7V1.

Application Field

Tantalum capacitors are a reliable and cost-effective solution for a number of different applications. They are often used in high-frequency components, power supplies, and decoupling capacitors. They are also used in radio frequency (RF) circuits, and in power supplies for consumer electronic devices. They can even be used as a power source for switching circuits in low-power circuits. In addition, tantalum capacitors are often used in pulse-shaping and oscillator circuits.

Working Principle

Tantalum capacitors have two electrically conductive, linked electrodes. An electrolyte is placed between the two electrodes, and an oxide layer is formed on the tantalum anode. This electrolyte is a liquid or gel material that serves as a conductive bridge between the two electrodes. When a voltage is applied to the device, an electric current is established, causing the oxide layer to grow on the tantalum anode and create an electrical connection between the two electrodes. This process is what enables tantalum capacitors to produce a large amount of capacitance in a very small space. The capacitance of a tantalum capacitor is determined by the size of the anode, the plate spacing between the electrodes, the voltage applied to the capacitors terminals, and the dielectric constant of the dielectric material between the two plates. The capacitance of the device increases as the plate spacing decreases and as the voltage applied to the electrodes increases. Conversely, the capacitance decreases if the distance between the plates is increased or the voltage applied to the electrodes is decreased.

Conclusion

Tantalum capacitors are essential components for nearly all electronic devices. They offer an efficient and reliable source of power in a wide variety of applications. Understanding the working principle and application field of a 199D395X9035C7V1 is essential for selecting the right capacitor for the right application. With proper knowledge and application, tantalum capacitors can be a great addition to any circuit or device.
