Nichicon Latest Technological Trends in Automotive Onboard Aluminum Electrolytic Capacitors

source: Nichicon article In the automotive and onboard automotive-related areas, the performance of equipment such as advanced driver assistance systems (ADASs) is progressing together with the advancement of space-saving mounting parts to ensure comfortable vehicle interiors. To this end, even individual capacitors must conform to harsh environments, miniaturization and high-capacity requirements. The latest technological trends […]

COTS in space: procurement strategy

source: Dan Friedlander at Intelligent Aerospace article The procurement of electrical, electronic, and electromechanical (EEE) components phase is common for all applications (commercial, automotive, military, space, etc.). Nevertheless, every application type has its own characteristics.

Defects in High-Voltage Ceramic Capacitors Found Acoustically

source: Power electronics article Acoustic imaging of high-voltage ceramic chip capacitors performs a non-destructive cross section through the capacitor—or, since the method is non-destructive, as many cross sections as desired. All of the imaging modes have the same purpose: to prevent flawed capacitors from causing field failures.

COTS in space: Addressing obsolescence, part I

source: Intelligent aerospace news January 19, 2018 By Dan Friedlander, Retired following 44 years in component engineering A component becomes obsolete when the original component manufacturer stops marketing it. Electrical, electronic, and electromechanical (EEE) components obsolescence hits the military, space, and commercial market. In the military, massive EEE components obsolescence occurred due in part to manufacturers’ decisions to […]

AVX Self-Balancing Supercapacitor Reliability Testing Performance

source: Power systems design news Supercapacitors are increasing in popularity amongst board-level components. In turn, there is now greater demand for supercapacitor reliability testing data, as sub-ppm component failure rates are critical for minimizing and eliminating PCB rework. Author: Eric DeRose, Field Applications Engineer; Bob Knopsnyder, Senior Development Engineer; and Bharat Rawal, Contractor/Retired Manager, BestCap […]

EEE COTS components in space: cost

source: Intelligent Aerospace article December 8, 2017 By Dan Friedlander retired following 44 years in component engineering Dealing with electrical, electronic, and electromechanical (EEE) components for any application is a complex, multi-disciplinary task. Those who are specialized in engineering should be aware of their creativity cost aspects. Design-to-cost (DTC) is a cost management technique to be applied from the earliest concept decisions. […]

COTS in space: hasty generalizations

source: Intelligent Aerospace article November 30, 2017 by Dan Friedlander Multiple articles I have authored on commercial off-the-shelf components in space applications have been met with more and more indications of fallacious, unpersuasive arguments. Some of the arguments are rooted in multi-year convictions, others are rooted in misunderstanding and/or misinterpretation of ambiguous, confusing, on-going official mixed […]

COTS in space: the 100 percent testing risk

source: Intelligent Aerospace article November 13, 2017  By Dan Friedlander, Retired following 44 years in component engineering The current European Space Agency (ESA) and National Aeronautics and Space Administration (NASA) approach to the use of Electrical, Electronic, and Electromechanical (EEE) commercial off-the-shelf (COTS) components in space applications continues to rely on heavy testing requirements. The official methodology […]
