Introduction to Tantalum Capacitors

Tantalum capacitors, also known as Ta-capacitors, are widely used in a variety of electronic products and components. Tantalum capacitors are made from a tantalum wire and feature a polarizing layer of manganese dioxide. The manganese dioxide layer acts as a dielectric between the tantalum wire and the metal electrodes, creating a polarized capacitor. Tantalum capacitors have high levels of reliability, durability, and temperature stability, making them ideal for applications that require a stable performance over an extended period of time.

M39003/01-2931 Application Field and Working Principle

M39003/01-2931 is a widely used tantalum capacitor. It is manufactured according to MIL-PRF-12105G specifications, and is categorized as a “pre-voltage capacitor” for use in high-voltage applications. The capacitor has a cylindrical shape, with an anode terminal at the center, surrounded by a cathode terminal. The anode wire runs from the anode terminal, and the cathode wire runs from the cathode terminal. The anode and cathode wires are connected to a dielectric, such as manganese dioxide, which provides a stable electrical field for the capacitor.

When current passes through the M39003/01-2931, it creates an electrical field between the anode and cathode, which is proportional to the applied voltage. The electric field between the anode and cathode helps to store energy in the capacitor, similar to how a battery stores energy. The dielectric layer in the capacitor serves to keep the electric field from overloading and hence helps to maintain stability within the capacitor. As the voltage increases, the electric field will also increase, allowing the capacitor to hold a greater amount of energy.

The M39003/01-2931 is used in many applications, such as automotive electronics, telecommunications, medical devices, and industrial electrical equipment. It is commonly used in power supplies, DC-to-DC converters, boards, and switches to provide the necessary voltage and charge storage. It also offers several advantages, including high temperature stability and low leakage current, as well as high reliability. The M39003/01-2931 is versatile in its application, and is a great choice for high-voltage applications.

Conclusion

M39003/01-2931 is an example of a widely used tantalum capacitor that is designed for high voltage applications. Its dielectric layer provides a stable electrical field, allowing it to store energy and maintain stability. Its temperature stability, low leakage current, and high reliability make it an attractive choice for automotive electronics, telecommunications, medical devices, and industrial electrical equipment. The M39003/01-2931 is a great choice for anyone looking for a high-quality and reliable capacitor for their application.
