Assessment of Supercapacitor’s Quality by Means of Low Frequency Noise

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 to asses quality of supercapacitors. Their quality is usually determined only by capacitance and/or...

Project for Energy Storage on a Chip for MEMS

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 are highly needed for autonomous microsystems and have to be integrated to enable an...

Commercial vs. Hi-Rel Tantalum Capacitors in Space Applications

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 these differences affect the materials, processes, and cost involved in their manufacturing.  This paper...

Parametric Failures in COTS Capacitors

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 presentation discusses two major reasons for parametric failures.  One is due to the marketing...

Lessons learnt at ESA from failure with commercial product/process in space applications

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 learn for the use of commercial product/process in space application. Title: Lessons learnt at...
