Niobium Capacitor Symbol

The symbol for a niobium capacitor is typically represented as "NbO" or "Nb2O5" in circuit diagrams and schematics. The abbreviation "Nb" represents the element niobium, while "O" stands for oxygen. Niobium capacitors use niobium oxide as their dielectric material and are known for their high capacitance density and low equivalent series resistance (ESR) compared to other types of capacitors. The specific chemical formula for niobium oxide used in these capacitors is generally Nb2O5, which refers to the compound formed by two atoms of niobium and five atoms of oxygen.
