Tantalum Capacitors

Tantalum capacitors are one of the most popular types of capacitors in the market, due to their low cost, high reliability and capacity to deliver high-frequency signals. The M39003/01-7228/HSD is an example of a tantalum capacitor, and its application field and working principle will be discussed in this article.

Types of Tantalum Capacitors

Tantalum capacitors are divided into three main types: wet, dry, and electrolytic. The wet type is a chemically processed version of the dry type, which uses a slug or pellet of tantalum and a solid metallic electrode. The dry type is composed of a solid layer of tantalum and a foil electrode, while the electrolytic type is composed of a dielectric compound and an electrolyte solution. The electrolytic type is more expensive but has higher capacitance than the other two types.

Application of M39003/01-7228/HSD

The M39003/01-7228/HSD is a wet, polar tantalum capacitor. Its main application is in pulse generating circuits, as it can provide a high-energy storage capacity as well as a stable pulse output. It is also used in charge-pump circuits, as its low equivalent series resistance (ESR) and dielectric absorption ratio (DAR) help reduce power dissipation.

The M39003/01-7228/HSD can also be used in high-voltage power supplies up to 200V. Its low leakage current and low dissipation factor make it an ideal solution for power applications that require high stability and reliability. In addition, it is also suitable for filtering applications and can be used as a decoupling capacitor in high-frequency circuits.

Working Principle of M39003/01-7228/HSD

The M39003/01-7228/HSD works on the concept of electrostatic charge transfer. When a voltage is applied to the capacitor, it creates an electric field between the two electrodes. This electric field then creates a charge on the capacitor’s dielectric material, which is then stored in the form of electrical energy. The dielectric material blocks the flow of current between the electrodes, but it still allows for the transfer of electric charge.

The M39003/01-7228/HSD has an operating voltage of 35V and a capacitance of 22µF. The reverse voltage rating is 7V, its dissipation factor is 0.05% max, and its leakage current is 0.10μA max. Its polarization is also important, as its capacitance is dependent on the direction of the applied voltage.

Conclusion

The M39003/01-7228/HSD is a wet, polar tantalum capacitor that is primarily used in high-frequency and high-voltage power supply circuits. Its low equivalent series resistance (ESR) and dielectric absorption ratio (DAR) combined with its high energy storage capacity and stable output make it an ideal choice for use in pulse generating circuits and other applications. It is also suitable for filtering applications, as well as being able to perform as a decoupling capacitor in high-frequency circuits. The working principle of the M39003/01-7228/HSD utilizes electrostatic charge transfer, which stores electrical energy on its dielectric material.
