• M39003/09-2027 Application Field and Working Principle

Tantalum capacitors are electrolytic capacitors and use tantalum pentoxide, or Ta2O5, as the dielectric material in the production of capacitors. They have a wide variety of industrial applications and are widely used to decouple, filter, store and protect electric circuits. The M39003/09-2027 series is a commercial grade of axial leaded Tantalum Capacitors designed for applications that require very low leakage current and high temperature stability.

• Working Principle

Tantalum capacitors are constructed from two metal electrodes, one of which is generally made of tantalum, separated by a layer of Ta2O5 dielectric material. Electrolyte is then applied to the electrode surfaces. Electrical energy is applied to the electrodes, which causes ions (ions of either tantalum or tantalum oxide) to migrate from one electrode to the other. The movement of the ions neutralizes the charge, thereby creating a capacitance between the two plates. The amount of capacitance is determined by the distance between the two electrodes and the size of the dielectric material, as well as the materials used in the electrolyte.

• Applications

M39003/09-2027 series Tantalum Capacitors are specifically designed for applications requiring low leakage current, such as telecommunications applications, medical equipment, military applications, and other high-energy applications. They are also used in electric circuits to store energy and to reduce supply irregularities in power electronics. The M39003/09-2027 series is especially designed to provide high temperature stability, making it ideal for environments with high temperatures and wide temperature tolerances. These capacitors are also popular in automotive and computer systems, as they can provide excellent energy storage and filtering.

• Advantages

Tantalum capacitors offer a number of advantages over other types of capacitors. They are able to operate at much higher temperatures than other capacitors, up to 200°C, and have high thermal stability. They also have very low ESR (Equivalent Series Resistance) and offer superior high frequency performance. Tantalum capacitors also have low leakage current, which makes them suitable for a variety of applications. Additionally, they can be constructed in very small sizes, making them ideal for space-constrained applications.

• Conclusion

M39003/09-2027 series Tantalum Capacitors are commercially designed for applications that require low leakage current and high temperature stability, such as military applications. They are able to operate at much higher temperatures than other capacitors, up to 200°C, and have high thermal stability. Additionally, they have very low ESR (Equivalent Series Resistance) and offer superior high frequency performance. Tantalum capacitors are also popular due to their low leakage current, which makes them suitable for a variety of applications. Overall, they are an excellent choice for applications that require advanced performance.
