Niobium Oxide Capacitors:

We offer niobium oxide NOJ, NOM, and NOS capacitors from Kyocera AVX.

What are niobium oxide capacitors?

Niobium oxide Oxicap® capacitors are solid electrolytic capacitors based on niobium oxide (nbo) anode material instead of traditional tantalum, offering non-tantalum material solutions. Niobium is a widely available material; it is the next element to tantalum in the periodic table, with many similar features. Several advantages over tantalum come from oxides of niobium, which are all stable with very specific performance relating to each oxide number. This is utilized in the unique Oxicap® manufacturing technology of processing niobium oxide powders as an anode base material.Niobium oxide capacitors have an extremely stable performance together with high reliability levels of 0.5%/1000hrs at 85°C or better, high safety technology with non-burning high resistance failure mode and high break down voltage. OxiCap® is available as low ESR, High CV, low profile, up to 125°C and multi-anode technologies. It is environmentally friendly and RoHS compliant technology in the same form, case size, and same or similar technical performance as standard tantalum capacitors. Capacitors are offered in voltage ratings up to 10Vr and high capacitance. Most of the series meet AEC-Q200 requirements. All niobium oxide capacitors are supplied in an orange colour encapsulating material.OxiCap® NOS Low ESR series of niobium oxide capacitors have been developed in order to offer significant Cost versus Performance value while targeting automotive requirements. AEC-Q200 compliant, excellent reliability level of 0.2%/1000 hrs within a temperature range up to 125°C and rated voltage up to 8V (for rail voltages up to 5.5V). These have the lowest ESR offerings within niobium oxide capacitors.OxiCap® NOM multianode product family: Very low ESR down to 30mΩ and high ripple current are the key parameters of the niobium oxide multianode construction within the E case package. Niobium oxide technology benefits such as high resistance and non-burn together with excellent reliability and reduced derating are maintained within this multianode series.OxiCap® NOJ capacitors use niobium oxide powder as the main anode electrode material for general applications. High reliability level (failure rate 0.5%/1000 hours); low ESR NOS devices have an even lower failure rate (0.2%/1000 hours) – even more reliable than tantalum capacitors. They are suitable for applications with rail voltages of up to 7V, such as in-cabin entertainment systems, seat position modules, airbag controls and more.
