AVX Corp. has developed a power
film capacitor series specifically for dc filtering applications. Designated
the FFLI Series, the advanced power film capacitor has a life expectancy of
100,000 hours, and unlike aluminum electrolytic devices, the FFLI Series
devices employ controlled self healing where end-of-life is defined as the time
taken for the capacitance to lose about 5 percent of its nominal value.
Series power film capacitors feature CV ratings of up to 3000F and 1900V dc/100Arms,
and can operate in temperatures of up to 95C. Qualified to IEC 61071 for power
electronic capacitors, the FFLI Series also meets IEC 60068-1 environmental
testing requirements and IEC 61373 shock and vibration tests.
AVX's new film metalized
products are useful for use in modular banks of capacitors for applications,
such as solar panel installations or wind turbine energy generators.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
