Heilbronn, Germany Vishay Intertechnology has extended its IHLP family of low-profile, high-current inductors with a new device that claims the lowest DCR/µH available in a compact 10.2 x 11.5-mm package with a low 4.0 mm height profile. With industry-leading specifications including DCR values down to 0.65 mOhm at 0.19 µH, the Vishay Dale IHLP-4040DZ-05 is a high-performance, space- and power-saving solution for dc-to-dc converter applications in end products including next-generation mobile devices; notebooks, desktop computers and servers; low-profile, high-current power supplies and point of load (POL) converters; distributed power systems; and field programmable gate arrays (FPGAs). The power inductor handles high transient current spikes without saturation and operates over a frequency range up to 5 MHz. Saturation current and typical DCR values range from 40 A to 60 A and from 1.55 mOhms to 0.65 mOhm, respectively, over an inductance range of 0.56 µH to 0.19 µH. Inductance tolerance for the new device is ±20%. The RoHS-compliant device is rated for an operating temperature range of -55 °C to +125 °C. It features a 100% lead (Pb)-free, shielded, composite construction that reduces buzz noise to ultra-low levels. Samples and production quantities are available now, with a lead time of eight weeks for larger orders. Vishay Semiconductor GmbH , Heilbronn, Germany. www.vishay.com.
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.
