Since almost a decade, supercapacitors (SC) were identified as promising high-power sources as they can bridge the gap between capacitors and batteries. SC have been found to be potentially attractive for several space power applications. ESA has conducted several...

Using polymer tantalum capacitors in Hi-Rel systems requires an assessment of the reliability characteristics of the parts. For this assessment, tantalum capacitors are typically subjected to reliability testing at temperatures and voltages exceeding their specified values, and the failure...

Cracks in MLCC ceramic capacitor are, unfortunately, a well know phenomena that can depend to several factors. It is believed to reduce the reliability of the capacitor leading to catastrophic failure like short circuit. When cracked capacitors are found...

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...

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 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...

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...

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...

Increase of capacitors’ energy density is of prime interest in number of today’s applications. High energy density, high voltage capacitors are especially needed in fast-growing segments such as automotive, renewable energy generation and transmission, medical etc. This paper evaluates...

Custom designed inductive components are widely used in the design of power conditioning equipment to individualize the conversion of energies for specific purposes. These components can be approved for application by individual qualification campaign either as a one off...
