Tantalum Capacitors

A tantalum capacitor is an electronic component that contains a solid electrolyte, typically made from tantalum and an oxide of tantalum, which serves as the dielectric material. Tatanum capacitors are a type of electrolytic capacitor, a power source component used as a building block in all types of electronics. The M39003/01-2507/TR is just one example of a tantalum capacitor. In this article, we will investigate the application field and working principle for this capacitor in particular.

Application Field

Tantalum capacitors are used in a variety of different applications that require a high energy density, vibration and shock resistance, and low equivalent series resistance (< 1 ohm). These capacitors are also used for temperature compensation, where a high stability is needed. The M39003/01-2507/TR is a Surface Mount unit – one of the most common types of capacitors in use today.

This type of capacitor can be found in many different applications, such as in high-frequency circuitry like mobile phones and radio transmitters, audio amplifiers, computer motherboards, pulse-forming networks, automotive and industrial systems, voltage regulation systems, and many more.

The M39003/01-2507/TR is an excellent choice for applications that require a small size with a high capacitance rating. This capacitor can also be used in high-frequency switching circuits since it has an excellent ESR (Equivalent Series Resistance) rating.

Working Principle

A tantalum capacitor works using the principle of electrochemical capacitance. This means that it has two conducting surfaces that are separated by an insulating material, or dielectric. The dielectric acts as an insulator between the two surfaces, allowing electric charge to pass between them.

In the case of the M39003/01-2507/TR, the dielectric is composed of a tantalum shell containing a tantalum oxide layer. This helps increase the capacitance rating and allows the capacitor to store a large amount of charge in a small space. Additionally, the tantalum shell improves the capacitor’s vibration and shock resistance.

When an electric field is applied to the capacitor, the voltage across the plates will cause electrons to flow from one plate to the other. This creates a net charge on the plates, which is equal to the applied voltage times the capacitance of the component. The voltage remains constant until the capacitance is discharged or the applied voltage is changed.

Conclusion

The M39003/01-2507/TR tantalum capacitor is a versatile component that can be used in many different applications. Thanks to its small size and high capacitance rating, it is ideal for high-frequency circuitry and pulse-forming networks. Additionally, its vibration and shock resistance make it ideal for use in automotive and industrial systems. It works using the principle of electrochemical capacitance, in which an electric field applied to the capacitor causes electrons to flow between its plates, creating a net charge.
