Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are small but reliable electronic components that are widely used in various circuits to store and discharge electrical energy. The M39003/01-5478/98 model is an especially reliable and versatile tantalum capacitor with a wide range of applications and a proven working principle.

Application Field

The tantalum capacitor is commonly used in situations where both a high voltage rating and a low profile are required, such as computers, consumer electronics, medical equipment, and military applications. These specialized applications also demand a high capacitance stability with respect to variations in temperature, humidity, and voltage. As such, the M39003/01-5478/98 utilizes advanced construction techniques to ensure superior electrical performance.At a minimum, this type of unit is rated for a maximum capacitance value of 4.7µF, a maximum working voltage of 25VDC, and a temperature range from -55°C to +105°C. The M39003/01-5478/98 also provides excellent flexibility with a variety of package sizes. This includes both standard 2- or 3-terminal configurations and non-standard configurations that allow additional flexibility for tight or non-standard layout areas.

Working Principle

The M39003/01-5478/98 utilizes a solid tantalum construction technique to achieve its desired electrical performance. This type of construction is similar to an electrolytic capacitor in that it relies on a chemical reaction between two isolated electrodes to create electrical energy. The two electrodes are the anode, which is typically made of activated tantalum, and the cathode, which is usually made of manganese dioxide.The electrical energy stored in the M39003/01-5478/98 is formed when an electrical bias is applied across the two isolated electrodes. This causes a chemical reaction that causes ions to migrate from the cathode to the anode, forming a thin layer of oxide over the anode. This thin oxide layer acts as an insulator, effectively separating the two electrodes while at the same time allowing for a very specific amount of capacitance to be stored.When the reverse voltage is applied across the two electrodes, the oxide layer is removed, and the capacitance is discharged. This discharge of electrical energy is what allows the M39003/01-5478/98 to be used in both high- and low-frequency circuits.

Conclusion

The M39003/01-5478/98 tantalum capacitor is an extremely reliable and versatile electronic component that is used in many different applications. It is uniquely designed for maximum capacitance stability in the face of varying temperature, humidity, and voltage values. The proven working principle of this tantalum capacitor allows it to store and discharge energy quickly and reliably, making it a valuable component for any circuit or application.
