Tantalum Capacitors: M39003/09-4056/TR Application Field and Working Principle

Tantalum capacitors, sometimes referred to as "tantalum electrolytics" or "polymer tantalum capacitors," are a type of electrolytic capacitor which uses tantalum as one of its components. They have significant advantages over other types of capacitors, including superior size, reliability, and lower cost. This article explores the application field, working principle, and features of the M39003/09-4056/TR tantalum capacitor.

Application Field

The M39003/09-4056/TR capacitor is suitable for use in high-reliability, long-life, and high-volume applications in the electronics industry, such as in consumer electronics, industrial control, and military applications. Its capacitance range (10 micF to 160 micF) makes it perfect for use in power supplies, audio equipment, televisions, automotive applications, and more. Furthermore, this capacitor is designed to meet all pertinent industry standards, including JEDEC, MIL-STD-202, and J-STD-18.

Working Principle

The M39003/09-4056/TR tantalum capacitor works on the same basic principle as other types of electrolytic capacitors. It has two electrodes, each made from a different material. One electrode is made from tantalum foil and the other is made from a porous carbon material. In between the two electrodes, a dielectric material is inserted. When the capacitor is connected to a power source, an electric field is created, which stores the electrical energy. The higher the capacitance, the more energy can be stored.

Features and Benefits

The M39003/09-4056/TR tantalum capacitor is a robust and reliable capacitor with many advantages and features. It offers superior volumetric efficiency, as it is highly compact while still offering a large capacitance range. Its excellent temperature coefficient makes it more resistant to temperature variations, which ensures higher reliability and better performance. Furthermore, the capacitor\'s superior energy density and self-healing make it suitable for pulse applications. The capacitor also has a high ripple current rating and ESR, making it highly capable in ripple current applications. Lastly, its low voltage drop behavior helps reduce power dissipation losses and reduces losses due to temperature variation, resulting in higher efficiency and longer system life with fewer system upgrades.

Conclusion

The M39003/09-4056/TR is a robust and reliable tantalum capacitor, perfect for use in high-reliability and high-volume electronics and automotive applications. It offers excellent volumetric efficiency, excellent temperature coefficient, superior energy density, self-healing, high ripple current rating, and low voltage drop, making it highly suitable for pulse, ripple current, and power applications.
