OxiCap™

OxiCap™ is a solid electrolyte capacitor available in standard EIA case sizes as a cost effective high performance alternative to aluminium and tantalum surface mount technologies. The OxiCap™ non-burn technology is based on the widely available NbO niobium oxide ceramic material. They are processed through the same manufacturing process as tantalum capacitors, and have electrical parameters similar to general tantalum specifications.
