Abstract:
This paper presents an overview of the key features of emerging capacitor technologies – tantalum, niobium metal and niobium oxide in order to give designers a better understanding of the potential applications and to guide their choice of component solutions for their individual requirements. The second part of the paper is targeted to a new type of solid electrolyte capacitor that has been developed based on niobium oxide powder material. Capacitors made from niobium oxide powder offer the designer many interesting features such as significantly reduced ignition failure mode, better load resistance, reduced cost, etc. The paper gives an overview of the current “state of the art” on this technology and also provides a key development roadmap for short term and future advancements such as low ESR niobium dielectric capacitors.
