A tantalum capacitor, also known as tantalum electrolytic capacitor, is an electrolytic capacitor which mainly consists of a tantalum pellet with an oxide on its surface as a dielectric layer. The M39003/09-0180/HSD is a surface-mount, conductively polymer tantalum capacitor with a maximum capacitance of 180μF and is typically used in many different applications.

Compared to other electrolytic capacitors, such as aluminum electrolytic capacitors and ceramic capacitors, tantalum capacitors offer a number of advantages. Primarily, they provide high capacitance per unit volume, making them ideal for applications requiring high capacitance in a small footprint. Additionally, since the dielectric layer is formed when the oxide is in direct contact with the electrolytic solution, they are more resistant to mechanical shock and vibration than other types of electrolytic capacitors.

The working principle behind a tantalum capacitor is relatively straightforward. When voltage is applied across the tantalum pellet, with the negative terminal connected to the solid pellet and the positive terminal connected to an electrolyte solution, ions from the electrolyte are attracted to the negative terminal. This creates an electric field within the dielectric layer, which then acts as a capacitor. The electric field is further reinforced due to the structure of the solid tantalum, allowing for a higher capacitance for the same size as other types of electrolytic capacitors.

Due to their high capacitance and small footprint, tantalum capacitors are often used in applications requiring high and reliable capacitance such as voltage regulation, filtering, power conversion, bypassing, and decoupling circuits. Additionally, with its superior resilience to shock and vibration, the M39003/09-0180/HSD is often used in applications subject to harsh environmental conditions such as portable electronics and automotive applications.

In conclusion, the M39003/09-0180/HSD is a surface-mount, conductively polymer tantalum capacitor with a maximum capacitance of 180μF. It is often used in applications requiring high and reliable capacitance, particularly for portable electronics and automotive applications. Furthermore, the superior resilience of the design makes it suitable for use in harsh environmental conditions. Finally, the working principle of the capacitor allows for a higher capacitance per unit volume than other types of electrolytic capacitors, allowing for more efficient use of space.
