Tantalum Capacitors

Tantalum capacitors are a type of industrial electric component providing small but effective capacitance for electrical circuit applications. They are built from a tantalum alloy of manganese with a porous oxide coating used as the dielectric, with an electrolyte as the second (conductive) electrode. The M39006/25-0116 series is a variant of this component, providing a high capacitance in a low profile, axial-lead-shaped design.

Application Field

Tantalum capacitors, with the M39006/25-0116 series used as an example, can be used for a wide range of circuit applications, from simple decoupling applications to complex, high-precision voltage reference designs. As they provide a high capacitance in a low profile form factor, they are also suitable for use in compact, high-density circuit designs.

Common applications for the M39006/25-0116 series include decoupling, filtering, energy storage, smoothing, and buffering. As they are very stable and efficient over a range of temperatures, they can also be used in high-temperature applications.

Working Principle

Tantalum capacitors work on the principle of electrical capacitance, which means that they store electrical charge and release it when needed. The dielectric material used in a M39006/25-0116 series capacitor is a porous oxide which acts as the barrier between the two electrodes. This allows the capacitor to store a greater amount of charge than a conventional capacitor.

When a voltage is applied to the component, electrons travel through the electrolyte of the anode from the positive electrode to the negative electrode, creating a charge. This charge is stored in the dielectric and can be discharged when needed. When the voltage is removed, the dielectric releases the stored energy slowly while the capacitor is discharging.

Conclusion

The M39006/25-0116 series of tantalum capacitors are capable of providing a wide range of voltage and capacitance values in a reliable and efficient way. The high capacitance in a low profile form factor leads them to be useful in a number of circuit designs and high-temperature applications. As a result, tantalum capacitors, such as the M39006/25-0116 series, are a reliable and versatile choice for many applications.
