EXTENDED RANGE NbO CAPACITORS THROUGH TECHNOLOGY AND MATERIALS ENHANCEMENTS

摘要

A new family of capacitors based on Niobium Oxide has established itself in many applications. The initial series of these capacitors had some limitations in Capacitance per Voltage in a given case size compared with leading tantalum capacitors. Recent developments resulting from the technology enhancement of materials and processes, which increased anode Capacitance Voltage (CV) efficiency has enabled a new range of NbO product. The paper presents and discusses the performance and reliability of such capacitors and their lead-free solder and surge robustness features. This, together with the ability to use the parts at lower levels of voltage derating is a very vital alternative to ceramic and tantalum capacitors and thus brings benefits to designers of the current electronic equipments.
