Niobium Oxide Capacitors are in stock at Tenco Electronics. A niobium oxide 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.Tenco offers inventory, pricing, & datasheets for Niobium Oxide Capacitors.
