source: H.C. Starck Tantalum and Niobium GmbH; ESA SPCD 2018 Symposium EPCI e-symposium library article Ta capacitors are the best choice when applications require highest capacitance (energy density) on miniature scale combined with high reliability, low ESR, and excellent stability over wide ranges of time and application temperature. Recently, the demand of high reliability capacitors withstanding harsher conditions especially with respect to higher application...

The influence of different polymer/carbon ratio to solution viscosity and conductivity were observed. Electrochemical behavior of produced electrodes was evaluated in triethylmethylammonium tetrafluoroborate (TEMABF4) in...

The main objective focused on the design, fabrication...

source: Exxelia SAS, ESA SPCD 2018 Symposium EPCI e-symposium library article The aim of this work is the development of miniaturized filtering multilayers ceramic capacitors, single or multi capacitance, from various designs, circular miniaturizes shapes, or custom-design shapes. These special designs, for the most reduced dimensions, are only accessible by green machining of the MLCC’s. This step is one of the most critical in...
