This investigation of breakdown conducted by AVX is mainly intended to find basic parameters describing the phenomena, as well as its impact on the reliability and quality of the final product that is a ‘good’ tantalum capacitor. Breakdown can be produced by a number of successive processes: thermal breakdown because of increasing inductance by Joule heating, avalanche and field emission break; an electromechanical collapse due to the attractive forces between electrodes’ electrochemical ...
AVX manufactures a range of passive electronic components and connector products. The company operates at a time when acronyms and ‘buzzwords’ are being increasingly used. This terminology guide is intended to help users understand the ‘technospeak’.
This paper from AVX 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 looks at a new type of solid electrolyte capacitor that has been developed based on niobium oxide powder material. Capacitors made from niobium oxide powder ...
New materials capable of operating at higher temperatures, new material processing techniques and new procedures for increasing material stability have been implemented in AVX’s THJ series to extend its continuous operating temperature up to 175°C while maintaining better reliability compared with the standard range of tantalum capacitors.
Surface-mount tantalum capacitors, like all electronic components, impose restrictions on pad (or land) design and solder processing to achieve minimum defects. This white paper from AVX discusses proper pad designs, and the reasons behind those designs, and outlines solder process constraints for wave and reflow soldering.
