source: Brno University of Technology CEITEC, AVX Czech Republic s.r.o., EPCI e-Symposium Abstract: Tantalum capacitors have been the preferred capacitor technology in long lifetime electronic devices thanks to the stability of its electric parameters and high reliability. However, long time application of elevated temperature and high electric field can result in capacitor leakage current increase in time. In this paper the effect of ions...

source: ASRC Federal Space and Defense (NASA), EPCI e-Symposium Abstract: Exposure of chip MnO2 tantalum capacitors to humid environments might result in increased ESR, leakage currents, and first turn-on failures.  However, there is a lack of literature data on the effect of moisture on reverse bias behavior of the parts. The presence of moisture can also result in pop-corning when a high water vapor...

Our glasses, our hand gloves, shirts, shoes etc., can be connected already today with our smartphones and can send commands to the machinery surrounding us. We want this comfort, and we are all looking forward to having Smart Homes.   Chip manufacturers have introduced a new generation...

source: Alter Technology, ESA ESTEC, EPCI e-Symposium Abstract: During the last decade, a growing number of applications demanding higher power electrical consumption have emerged in some industrial sectors such as in the military, automotive or space ones. Consequently, electrical components with higher temperature range and rating voltage operation are needed. In addition, the good thermal characteristics of Silicon Carbide (SiC) and Gallium Nitride (GaN)...

Active layer is deposited on a flexible substrate by new deposition technique called Aerosol Jet. The deposition technique remove deficiency of today’s common used deposition technique, where it is very difficult to deposit a thin homogeneous layer of carbon nanotubes. The...
