Tantalum Capacitors: M39003/01-2620 Application Field and Working Principle

The M39003/01-2620 is a tantalum capacitor, a type of electrochemical capacitor manufactured from tantalum and typically used in the electronics industry. It is a general purpose surface mount capacitor, with higher volumetric efficiency and smaller case size being its key advantages and most commonly used in portable and miniature electronics. This article will discuss the application fields and working principle of the M39003/01-2620.

Applications

The M39003/01-2620 is an ideal capacitor for most general purpose and portable electronics, as its small size, high volumetric efficiency, and relatively low cost make it an attractive choice for these applications. It can be used for power supply smoothing, signal smoothing, and decoupling. It can also be used in automotive electronics, medical devices, digital circuits, instrumentation, and other portable and miniature electronics.

The M39003/01-2620 is particularly useful in power supply systems, as it is capable of delivering higher capacitance in a smaller size than alternative solutions. Its relatively low ESR (Equivalent Series Resistance) also makes it perfect for high-current applications, allowing it to deliver more power in less space. When used in power supplies, the M39003/01-2620 is effective at filtering out undesired high frequency noise and increasing ripple current capacity.

The M39003/01-2620 is also suitable for coupling and decoupling circuits, such as DC-DC converters, audio amplifiers, and computer circuits. Its low ESR also makes it well suited for high-current applications, where it can effectively filter high frequency noise and reduce power dissipation.

Working Principle

The M39003/01-2620 is a type of electrochemical capacitor, consisting of two electrodes and an electrolyte. The electrodes are made of a highly porous or sintered tantalum material, while the electrolyte is normally an organic solid or gel. The tantalum capacitor works in a similar fashion to other electrochemical capacitors, such as the aluminum electrolytic, in that a voltage applied to the device creates an electric field, causing ions to move from one electrode to the other. This process creates a charge imbalance between the two electrodes, and the capacitance of the device is determined by the amount of charge stored by this imbalance.

The M39003/01-2620 differs from other types of electrochemical capacitors in that it has a much lower ESR, due to the use of a more highly porous tantalum material. This porous material allows ions to move more freely, reducing the voltage drop across the capacitor and consequently lowering the impedance. The relatively low ESR of the M39003/01-2620 makes it well suited to high-current applications.

Conclusion

The M39003/01-2620 is a tantalum capacitor suitable for a wide range of applications in the electronics industry. It has a higher volumetric efficiency and a smaller case size than other capacitors, making it perfect for use in portable and miniature electronics. It is also notable for its low ESR, which makes it well suited to high-current applications such as power supplies and audio amplifiers. The working principle of the tantalum capacitor is based on the ability of ions to move from one electrode to the other, creating an electric field that creates a charge imbalance and determines the capacitance of the device.
