American Bright Optoelectronics announced the BL-Hxxx7A-TRB series of small, low current surface mount LED in 0402 (1.0 mm × 0.5 mm × 0.4 mm) package size. The LED is compatible with infrared and vapor phase reflow solder processes and provides compatibility with industry standard automatic placement equipment. The series is RoHS compliant and compatible with industry accepted lead free processes.
Energy News: CNN posted a very solid overview story about the state of solar power. The technology, if we lived in a proverbial vacuum, can already provide all the world's energy needs by installing panels in a small corner of the Sahara. But in the real world, cost and security are
Thermocouples provide the key components of thermoelectric cooling modules. A thermocouple comprises a p-type and an n-type semiconductor element connected by a metal plate. Electrical connections at each end of the p- and n-type material complete an electric circuit. When a source supplies a current, thermoelectric cooling occurs. The thermocouple then "pumps" heat by cooling one side and heating the other by what is known as the Peltier effect.
National Semiconductor Corporation announced the addition of two new, high-efficiency Simple Switcher synchronous buck regulators to its PowerWise energy-efficient product family. The highly integrated LM3102 and LM3103 are said to be the industry’s first synchronous buck regulators to feature an input voltage range up to 42V. The ICs are optimized for powering digital integrated circuits (ICs) in industrial and telecommunication applications. Integration of MOSFET switches and the use of small inductors enables a reduced system component count and very small solution size
Energy News: More than a third of enterprise CIOs don't monitor their corporate energy use, according to an Economist Intelligence Unit report, commissioned by IBM. "Although concerns about energy efficiency and global warming are now high on the political agenda, the spotlight
Supertex introduced the HV9982 three channel LED driver IC designed to provide high LED current accuracy through closed-loop control of the output currents. It is designed for applications using RGB LED backlighting or multiple strings of white LEDs. The device employs a fixed frequency, closed-loop, current mode control architecture that ensures stable operation over a wide range of input and output voltages.
Advanced Power Solutions announces an extension of it’s APS63VI series to include triple output models. This family of 2" × 4" open-frame power offer a low profile of only 0.92”. The supply features Class B Emissions and worldwide safety approvals including UL/cUL60950-1 / EN60950-1 and bear the CE Mark (LVD). These power supplies offer efficiencies of up to 80 to 89.5 percent typical and an operating temperature of
Minmax's MSKW2000-Series 5W DC/DC converters are housed in a "gull-wing" SMT package and meet 245°C/10sec in solder-reflow for lead free process. The series consists of 21 models that operate over input voltage ranges of 9V DC to 18V DC, 18V DC to 36V DC and 36V DC to 75V DC which provide precisely regulated output voltages of 3.3V, 5V, 12V, 15V, ±5V, ±12V and ±15V DC. The -40°C to +71°C operating temperature range makes it suitable for data communication equipments
Aitech Defense Systems, Inc. announced an environmentally sealed, 2-slot 3U CompactPCI enclosure that provides desirable flexibility and performance. In addition to its rugged environmental properties, the compact and lightweight E192 incorporates a modular and removable power supply, making the enclosure suitable for harsh mechanical, climactic, chemical and electrical stresses typically encountered in rigorous embedded applications.
