at al.., Low ESR and Low Profile Technology on Niobium Oxide, AVX CARTS

Increasing demand for tantalum capacitors at the end of last millennium accelerated simultaneously the search for new technologies, which were able to solve the drawbacks of tantalum technology – the long source chain, tantalum cost and its susceptibility to certain low ppm level of thermal runaway failures. One of the newest technologies, NbO capacitors have launched into the market during the last 2 years. It’s significant similarities to tantalum capacitors with such benefits as non burning failure mode, lower cost, surge robustness and excellent reliability is raising other questions to other NbO potential, like voltage range, need for derating,lower ESR and miniaturisation. This paper summarises the latest in new NbO technology capabilities
