Tantalum capacitors are widely used in a variety of fields due to their special physical and chemical characteristics. The M39006/09-8058 series of tantalum capacitors provides higher voltage ratings, smaller sizes, and generally better performance than other commercially available tantalum devices. This article will discuss the application field and working principle of M39006/09-8058 tantalum capacitors.

Application Field

M39006/09-8058 tantalum capacitors can be used in various fields both for commercial and industrial. Common applications include decoupling in power supplies, signal filtering, and high-frequency communication filters. Its application also includes medical instruments, military equipment, communication equipment, industrial automation, audio and video equipment, electronic toys, power control cabinets, automotive electronics, and other fields.

Working Principle

The M39006/09-8058 series of capacitors consists of tantalum powder as the anode, an oxygen-free copper or stainless steel terminal as the cathode, a plastic spacer, and a manganese dioxide electrostatic film as the electrolyte medium. When the capacitors are in use, an electric field is generated between the anode and the cathode; when an alternating voltage is applied, a capacitive current is generated. The manganese dioxide electrostatic film acts as a dielectric material between the two electrodes and the surface area of the foil determines the capacitance. The other internal components affect the volume and moving ability of the dielectric. With the increasing surface area, the capacitance is also increasing.

The dielectric material in tantalum capacitors also provides a self-regulating process that regulates the voltage across the terminals, reducing the overall power loss over time and improving the life of the device. In addition, the tantalum powder used on the anode also helps to dissipate heat, resulting in increased service temperature.

Conclusion

The M39006/09-8058 series of tantalum capacitors is designed to provide higher voltage ratings, smaller sizes, and generally better performance than other commercially available devices. They can be used in various fields ranging from medical instruments to power supplies. The working principle of the capacitors is based on an electric field between the anode and the cathode, resulting in a capacitace and self-regulating process. The service temperature and life of the device are also improved with the tantalum powder used on the anode.
