The reliability and failure modes in surface mount Solid Electrolytic and Polymer Tantalum capacitors were investigated using the parts manufactured with conventional technology and flawless technology (F-Tech) that suppresses typical defects such as crystalline inclusions in the amorphous matrix of the tantalum oxide dielectric. The paper was presented by Yuri Freeman, KEMET Electronics Corporation. USA at the 3rd PCNS 7-10th September 2021, Milano, Italy...

Selection of electrolytic capacitors is mainly based on their reliability. Beside this property, the evaluation of environmental performances of such devices is crucial due to their wide dissemination and utilization of critical raw materials for their production. Starting from the environmental analysis of the stages of selection and supply of raw materials, it is possible to improve the sustainability of the manufacturing process of...

The purpose of the work is to propose a method for predicting the reliability of a capacitor by leakage currents (DCL), which allows predicting the behavior of DCL, already at the initial stages of anode manufacturing, based on the mechanical tests, which significantly reduces the time and cost at its manufacture. The paper was presented by Vladimir Azbel, independent consultant, Israel at the 3rd...

Polymer capacitors replaced electrolytic aluminum and manganese tantalum capacitors in many applications. While this trend was driven mainly by low equivalent series resistance (ESR) requirements in the past, high reliability performance is additionally requested for polymer capacitors nowadays. The development of new conductive polymers has opened the field of high reliability applications for polymer capacitors such as automotive, space and telecommunication. Even in consumer...

Carbon is one of the basic elements that has been used in electronics for a long time. Carbon occurs in various forms (allotropes) such as graphite, diamond, carbon nanotubes or graphene. In particular, carbon nanotubes and graphene are increasingly used in the field of electronic components and sensors. Carbon nanotubes can be modified by organic or inorganic substances and based on this to change...
