Delivering power to a tunable laser, Advanced Interconnections’ Mezza-pede 1 mm SMT connector system passes mixed flowing gas (MFG) testing for use in 1 mm pitch micro board-to-board and flex cable-to-board applications. The RoHS-compliant device presents a mated height of 4 mm, a pin and lead frame design, and screw-machined terminals with multi-finger contacts having a
I'll begin this column with a recommendation: Start kits with a set of basic hand tools. When my son went to college, he had tools to hang pictures, connect TV sets and CD players, and tighten desks and shelves. As a result, he met most of the people on his co-ed floor. When our daughter went to college she got a tool kit, too. I suggest Phillips and flat-blade screwdrivers, pliers, diagonal cutters, wire strippers and a couple of adjustable wrenches. Later you could add a set of nut drivers, sockets wrenches and an inexpensive soldering iron.
Isolating and suppressing common-mode and differential-mode interference, Epcos’ AS249, AS247, and AS066 magnetic inductor modules perform in LAN applications, such as 10/100 Base-T, 1000 Base-T, and PoE. The components demonstrate insertion loss of -1 dB, return loss of -16 dB, crosstalk of -40 dB, and electrical isolation withstanding a breakdown voltage of
You can think of direct digital synthesis as a technique that lets a digital value control the frequency of a sine wave. At its simplest, a DDS circuit involves a binary counter, a ROM programmed with equally spaced sine values for one full wave, and a digital-to-analog converter to convert the stored sine values to voltages. The frequency of the counter's clock determines the sine-wave frequency, but that's an inflexible arrangement.
Covering the nominal application voltages of 12 VDC, 24 VDC, and 48 VDC, XP Power’s JCJ08, JCJ10, and JCG12 DIP-24-packaged DC/DC converters exhibit input voltages from 9 VDC to 18 VDC, 18 VDC to 36 VDC, and 36 VDC to 75 VDC. The 1.25” × 0.80” × 0.40” units come in single output models with voltages of 2.50 VDC, 3.30 VDC, 5 VDC, 12 VDC, or
Regular Efficiency Zone readers know that photovoltaics is a very inefficient technology. While the technology is environmentally-friendly, and the energy source (the sun) will be viable for billions of years, the conversion process (and viability) is undercut by a number of factors. These include shade, dirt, and panel-to-panel mismatch. In addition, detractors of the technology point to its high cost, but this is a socio-economic factor that won’t be solved by science alone. But scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have made a huge technological leap.
