Tantalum Capacitors Reliability, Leakage Current Stability Prediction and Cost Reduction by Anode Characterization During Manufacturing Process

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...

Reaching the Next Level of Reliability for Polymer Capacitors

Reaching the Next Level of Reliability for Polymer Capacitors

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...
