Embodiment Construction
[0025] The embodiment of the present invention provides a chip-type niobium oxide solid electrolytic capacitor and its manufacturing method. The specific volume is 60,000-120,000 UuF.V / g, and the niobium monoxide powder with an oxygen content of 14.5-15.5% is used as a raw material. / CC pressing density is pressed into a compact, and the anode compact is formed by vacuum sintering, and then a chip-type niobium oxide electrolytic capacitor is prepared by forming a DC voltage dielectric layer, cathode preparation and packaging. Compared with tantalum capacitors or pure niobium capacitors, this niobium oxide electrolytic capacitor has greatly improved performance and safety, and can be used in various circuits, such as switching power supply circuits with large surge voltage and current. , will not burn and explode, and the capacity and loss parameters remain basically unchanged, and the large current passing through can be limited. Continuous breakdown can be effectively avoided...
