Tantalum Capacitors

M39003/01-5292/HSD are tantalum capacitors, which are widely used elements in electrical circuits. This type of capacitor is composed of pure tantalum, which is a highly conductive metal. The tantalum capacitor is ideal for a variety of applications due to its long-term stability, low leakage current, highly temperature stable environment, and high energy density.

Application Field

Tantalum capacitors are one of the most widely used components in electronic devices ranging from portable devices and smart phones to servers and computing systems. Their popularity can be attributed to their wide range of advantages.

Tantalum capacitors have lower equivalent series resistance (ESR) than any other type of tantalum capacitors, making them useful for high frequency applications such as power supplies. They can also be used in applications where a low profile component is needed, since they are much thinner than other types of capacitors. Furthermore, they are ideal for use in audio circuits, as they have low distortion levels. They are also widely used in automotive, medical and military applications.

Working Principle

The working principle of a tantalum capacitor is based on the electrochemical interaction of an electrolyte, an anode and a cathode. The electrolyte is a liquid which reacts when traversed by an electric field, forming the anode and the cathode. A dielectric layer of oxide is formed between the anode and cathode. When a voltage is applied, the static electricity is stored in the dielectric layer, and the current that flows is very low, which reduces the dissipation of energy.

The electrodes of a tantalum capacitor are mainly composed of a thin layer of tantalum with an oxide layer that acts as a dielectric forming part of the capacitor. A dielectric layer typically consists of a complex solid solution of oxide, where the anode contains the metal ions and the cathode contains the electrolyte. The combination of tantalum and oxide creates a layer with a high dielectric constant, which is what allows the capacitor to store significant amounts of energy.

Tantalum capacitors tend to have an extremely long life span, and are therefore ideal for long-term use. This is because the metal composition of the capacitor is essentially inert and does not degrade over time. The capacitor also benefits from having a very low internal resistance, which is beneficial in reducing power losses in applications where current is being drawn for extended periods of time.

Conclusion

M39003/01-5292/HSD are tantalum capacitors which offer a wide variety of advantages for electronic applications. These capacitors are well suited for applications which require high frequency, low distortion, and a long lifespan. The combination of tantalum and oxide creates a layer with a high dielectric constant which allows the capacitor to store large amounts of energy for extended periods of time.
