Abstract:
This paper cites the characteristics of tantalum capacitors, applications and application characteristics of aluminum capacitors and multilayer ceramic capacitors. It analyzes the new trends that the chip-based and miniaturization tantalum capacitors led capacitor grade tantalum powder to higher capacity. It describes the challenges of the demand for high reliability in high-voltage tantalum powder of aviation, aerospace and military field voltage capacitor to a higher voltage and lower ESR direction. It reviews the application development process of the capacitor tantalum powder with high capacitance tantalum powder, high voltage tantalum powder and medium voltage (flake) tantalum powder. It analyzes the performance, product and key technologies current status of high capacitance tantalum powder, high voltage tantalum powder and medium voltage(flake) tantalum powder of the classical methods of potassium tantalum fluoride (K2TaF7) sodium metal reduction, electron beam melting , ball milled production. For 30-80k μ FV/g tantalum powder，the influence factors of withstand voltage performance have been analyzed. Finally，it presents new technologies, devices, products morphology, performance, advantages and disadvantages of the high capacitance tantalum powder and high voltage technology. On the basis of capacitor grade tantalum powder, this paper point out sustainable development ideas of higher capacitance and higher voltage for tantalum capacitors.
