Film capacitors in power electronics find a wealth of applications and excel when high ripple current ratings are required or when the environment imposes over-voltage stress
A deep-dive into the capacitor and resistor raw materials supply chain, examining availability and expected continuity of supply over the next five years is posted here
The ExoMars 2016 Trace Gas Orbiter (TGO) and an ESA-built EDM stationary lander called ‘Schiaparelli’ will be launched in March 2016. The TGO will deliver the stationary lander and then proceed to map the sources of methane and other gases on Mars, and in doing so, will help to select the landing site for the ExoMars 2018 rover (to be launched in 2018 on a Russian heavy lift Proton launch vehicle).

Failures in plated through vias (PTV) can be related to different causes, some of them discussed elsewhere. Amongst them, thermomechanical fatigue is the most frequent failure mechanism observed in plated through systems. Hence, the present post analyses the typical thermally induced failures in PTV architectures.
Power transistors based on gallium nitride and silicon carbide impose very high demands on DC link capacitors. TDK has now developed a dielectric that allows such film capacitors to be used up to +125 °C instead of +105 °C while optimizing its winding structure.
Eurospace is a trade association of the European space industry. It is a European nonprofit organization created in 1960. Eurospace member companies today represent about 90 per cent of the total turnover of the European space industry.
In acoustic microscopy, resolution and inspection depth is an inversely related parameter that depends on the probe frequency and the characteristics of the involved materials. Therefore, the inspection frequency must be carefully selected in order to optimize the accuracy without decreasing the inspection depth below the specimen thickness. Suitable selection of the inspection parameters provides:
Detection of ultra-thin (submicrometric) delamination in multilayer systems.
Micrometric lateral resolution. In acoustic microscopy, resolution and inspection depth is an inversely related parameter that depends on the probe frequency and the characteristics of the involved materials.
Mars 2020 SuperCam calibration target carries a complex set of standards for imaging calibration, mineral identification, and chemometric calculations or spectral references to calibrate and evaluate the health of the instrument basic.
Plated Through Vias (PTV) are critical elements in PCB systems and special care must be paid during their inspection in order to ensure the reliability, as they are one the main factors that determine the PCB Quality.
The functionality and reliability of PTVs are dictated by: the plated through hole architecture (height/diameter), plating (thickness and quality) and other PCB general characteristics (materials and design).
