Fleet, UK AVX 's new series of X8R ceramic capacitors delivers high efficiency in elevated temperature applications, its dielectric material offering a capacitance variation of 15% between -55 °C and +150 °C. Devices are available in case sizes 0603 and 1206, with a capacitance range from 270 pF to 0.47 µF respectively. Larger capacitance devices (2.2 µF and above) are under development in case size 1210. The rated voltage is 16, 25 and 50 V. The X8R capacitor is specially designed for high temperature environments such as automotive under-bonnet sensors in areas including the engine compartment (on engine or gearbox), the chassis (near breaks, hydraulics) or the cabin itself (roof exposed to strong sun). Electronics used in oil exploration equipment will also benefit considerably from the X8R. The capacitors are available as standard and automotive AEC-Q200 qualified parts.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
