Niobium Oxide Capacitors

Niobium oxide capacitors are an electrolytic (polarized) capacitor type incorporating oxides of niobium as anode and dielectric materials, with a manganese oxide cathode system. Developed in response to a tantalum shortage, their properties and behaviors are similar to conventional Ta-MnO2 capacitors, with a narrower range of available capacitance and voltage values and a greatly reduced likelihood of device failure resulting in ignition.
