source: Brno University of Technology CEITEC, EPCI e-Symposium Abstract: Degradation of supercapacitor (SC) is analyzed by accelerated aging test. Evolution of SC parameters is determined before the aging test, and during up to 8 x 105 cycles of both 75% and 100% energy cycling. Capacitance fading, equivalent series resistance (ESR) ...
source: University “Politehnica” of Bucharest, EPCI e-Symposium Abstract: Current trends in supercapacitor technology (principially in lowering series discharge resistance) have promoted the devices into roles parallel to, or replacing traditional batteries. In cases where power consumption is low, supercapacitors are an attractive alternative, completely eliminating batteries and further offering higher ...
source: Gdańsk University of Technology, EPCI e-Symposium Abstract: Low frequency noise is a well-known tool for quality and reliability assessment of electronic devices. This phenomenon is observed in different electrochemical devices as well (e.g., smart windows, electrochemical corrosion processes). Thus, we can assume that the same tool can be used ...
source: FEEC Brno University of Technology, EPCI e-Symposium Abstract: A new project with a budget of 262 thousands Euro was motivated by the lack of micromachined energy storage solutions that can be integrated with a MEMS harvester on a chip with a specific circuitry. These key components of the system ...
source: Kemet Electronics, EPCI e-Symposium Abstract: There are several grades of electronic components that depends on their long-term reliability and resistance to harsh environments, including commercial, automotive, high reliability COTS, and MIL. This paper describes the differences in qualification and testing requirements for different grades of Tantalum capacitors and how ...
source: ASRC Federal Space and Defense (NASA,USA), EPCI e-Symposium Abstract: Insertion of COTS components into hi-rel systems require extensive environmental testing of the parts that often results in parametric failures. Based on experience with commercial and hi-rel PME and BME ceramic capacitors and polymer and MnO2 cathode tantalum capacitors, this ...
source: ESA, EPCI e-Symposium Abstract: The presented presentation slides are prepared based on ESA long term experience with passive components use in space environment. Several failures and investigations during the last years linked with the use of commercial components or commercial manufacturing process are reported. We will share some lesson ...
source: Valeo Autoklimatizace k.s., EPCI e-Symposium Abstract: Automotive industry has been facing exciting and important challenges in recent years. It is not only the move from classic combustion engine cars to hybrid or fully electrical vehicles. Much more is going on in the field of Advanced Driver Assistance Systems (ADAS) ...
source: Serma Technologies, EPCI e-Symposium Abstract: SERMA TECHNOLOGIES is presenting failure statistics of all return parts analyzed during the last 5 years. For each family of passives components ( ceramic, tantalum, film capacitors and resistors) , percentage of defect will be given. The origin of defect (suppliers, board assembly process, ...
source: AVX Corporation, EPCI e-Symposium Abstract: In common with commercial applications, demand for established reliability solutions with higher bulk capacitance and lower ESR continues, along with the need for increasing the volumetric efficiency and reducing real estate / payload. Interestingly, voltage trends remain fairly stable within avionics and aerospace as ...
