J-Type voltage-controlled crystal oscillator features a 3 or 5V supply voltage, frequencies to 155 MHz, pullability to 150 ppm, phase jitter less than 20 ps, and a 20 ppm stability over the temperature range. The J package also has six leads with a tri-state option.
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.
