Working Principle

Tantalum capacitors work by storing energy in the form of an electrical charge. This is done through the use of two conductors, a dielectric material, and an electrolyte. The dielectric material is used to insulate the two conductors from each other. The electrolyte provides a path for charge to flow between the two conductors. When a voltage is applied across the two conducors, a current will flow through the electrolyte, creating a charge on each of the conductors. When the voltage is removed, the charge stored in the capacitors will remain until it is discharged.

The M39006/25-0139 is designed to be able to handle high voltage surge conditions. The capacitor consists of two internal layers. The bottom layer is made of nickel-plated copper and is connected to the positive terminal of the capacitor. The top layer is made of a conductive material that is insulated by a very thin dielectric layer. This layer acts as the storage medium for the charge and is connected to the negative terminal.

When a voltage is applied to the capacitor, the charge on the top layer will be transferred to the bottom layer. This causes a current to flow through the electrolyte, thus storing energy in the form of an electrical charge. As the voltage is increased, the amount of charge stored in the capacitor increases as well. When the voltage is removed, the charge stored in the capacitor will remain until it is discharged.

The M39006/25-0139 has a variety of features that make it an excellent choice for high-reliability industrial applications. Its high temperature stability, low ESR, and excellent DC surge handling make it ideal for a wide range of applications.

Conclusion

The M39006/25-0139 is a highly reliable surface-mount tantalum capacitor that is designed to meet stringent requirements for environmental, mechanical, and electrical characteristics in high-reliability industrial environments. It is an excellent choice for a wide range of applications due to its low ESR, high stability, and excellent DC surge handling.
