OxiCap® NOJ Series

NOJ OxiCap® capacitors use Niobium Oxide powder as the main material for the anode electrode 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 etc.

Niobium oxide has much higher ignition energy (200 times) and much lower burning rate than pure metal materials such as Tantalum or Niobium. This feature means that OxiCap® capacitors will not burn up to the category voltage. A further benefit concerns overload. A typical failure mode is high resistance (typically 20 to 200kΩ) after overloading by voltage spike or high current surge, which can result in increased leakage current and reduced capacitance. However, an OxiCap® capacitor will continue to provide full capacitance and functionality – albeit at the expense of increased power consumption. NOJ Series capacitors are designed as environmentally friendly and RoHS compliant product.
