Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor, a passive electronic component. It is composed of two electrodes, a cathode and an anode, separated by an electrolyte, typically a solution of aluminum oxide. The most common tantalum capacitor construction uses tantalum powder for the anode, a solid conductive polymer for its dielectric, and a solution of manganese dioxide in an organic solvent for its electrolyte.

M39003/09-2023 Application Field and Working Principle

Application Field

The M39003/09-2023 tantalum capacitor is designed to be used as a decoupling capacitor in MIL-PRF-55365 approved equipment. It features low equivalent series resistance (ESR) values for superior electrical performance, and is approved for operation in equipment with 25V DC and lower. Additionally, the M39003/09-2023 comes with a standard low-inductance wrap & fill style case.

Working Principle

Tantalum capacitors are electrolytic capacitors, so they operate on the same principle as other electrolytics. Electrons are transferred from the anode to the cathode by an electrolyte, creating a dielectric barrier between the conductive plates. This allows for a steady flow of electrons, which results in a steady current. The tantalum capacitor also works similarly to other capacitor types in that it can store a charge, and then release it again.

However, the key difference between a tantalum capacitor and other capacitor types is that the dielectric material, usually an aluminum oxide, is formed in-place by the formation process. As a result, the capacitance of a tantalum capacitor will be higher than that of most other capacitor types, and it will also have a very low ESR (Equivalent Series Resistance). This makes the M39003/09-2023 ideal for applications where superior electrical performance is necessary, such as decoupling or power supply bypass.

The M39003/09-2023 also features standard 5% and 10% tolerances, allowing for superior accuracy as well as better temperature and voltage precision. All of these features combine to make the M39003/09-2023 an ideal choice for a variety of applications in the 25 Volt DC or lower range.

Conclusion

The M39003/09-2023 tantulum capacitor is an ideal choice for applications where superior electrical performance, excellent temperature and voltage precision, and reliable operation are necessary. Its low ESR and high capacitance make it a great choice for decoupling and power supply bypass applications. With its MIL-PRF-55365 approval, the M39003/09-2023 is an excellent choice for both commercial and industrial applications.
