Niobium capacitor
A niobium electrolytic capacitor is a polarized capacitor whose anode electrode (+) is made of passivated niobium metal or niobium monoxide on which an insulating niobium pentoxide layer acts as the dielectric of the niobium capacitor. A solid electrolyte on the surface of the oxide layer serves as the second electrode (cathode) (-) of the capacitor.Niobium electrolytic capacitors are passive electronic components and members of the family of electrolytic capacitors.Niobium capacitors are available as SMD chip capacitors and compete with tantalum chip capacitors in certain voltage and capacitance ratings. They are available with a solid manganese dioxide as well as a solid conductive polymer electrolyte. Niobium capacitors are polarized components by manufacturing principle and may only be operated with DC voltage in correct polarity. Reverse voltage or ripple current higher than specified can destroy the dielectric and thus the capacitor. The destruction of the dielectric may have catastrophic consequences. Manufacturers specify special circuit design rules for the safe operation of niobium capacitors.Niobium capacitors were developed in the Soviet Union in the 1960s. Since 2002 they have been commercially available in the West to take advantage of the lower cost and better availability of niobium compared with tantalum.
