WESTWOOD, N.J. Series MPP single- and three-phase power-correction capacitors and assemblies from Seacor Inc. are designed with extremely low-loss polypropylene dielectrics, resulting in stable electrical characteristics and life expectancies up to 100,000 hours. Single-phase units operate from 400 to 600 V with capacitances ranging from 6.7 to 497microfarad. Three-phase models operate at 400 to 600 V with capacitances ranging from 3 x 3 to 3 x 166 microfarads. Devices are designed for highly stressed ac use, and function to 70degreesC without affecting capacitor life.
Prices depend on specific power-factor correction, but start at approximately $35.
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.
