Gowanda Electronics recently achieved qualification to the military’s MIL-PRF-83446 (/36A and /37A) for its ML0603 and ML0805 series of RF surface mount wire wound ceramic core chip inductors. These inductors meet this particular Department of Defense specification and have application within military, aerospace and defense communities.
According to the manufacturer, the ML0603 Series is QPL approved to MIL-PRF-83446/36A and provides inductance from 1.8 to 270 nH, Q Min from 16 to 40, SRF MHz min from 600 to 6000, DCR Ohms max from .07 to 1.78 and current rating DC mA from 195 to 1000. The ML0805 Series is qualified to MIL-PRF-83446/37A and provides inductance from 2.2 to 2200 nH, Q min from 15 to 65, SRF MHz min from 40 to 6000, DCR Ohms max from .08 to 5.0 and current rating DC mA from 140 to 1000. Both series are wire wound coils with ceramic cores and gold terminations. Operating temperature for each series is -55°C to +125°C. The inductors are available in tape and reel and are suitable for reflow soldering.
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.
