The YEV Series of 3, 6, and 10 amp vertically-mounted, Point-of-Load (POL) DC-DC converter products from Power-One offers an extended operating temperature range option of -40ºC to 85ºC. The POLs utilize advanced topologies to deliver up to 94 percent efficient power conversion in communications and server applications
The U.S. should build 100 more nuclear plants rather than spend "billions in subsidies" for renewable energy if it is truly committed to lowering electric bills and having clean air, the Republicans say. In the party's weekly radio and Internet address, Sen. Lamar Alexander said the United States should follow the example of France, which promoted nuclear power decades ago
Designed to offer a low cost solution for low resistance value requirements where high temperature operation and low TCR are less important, the CSR / CSRN Series of thick film current sense chip resistors from Stackpole provides a TCR that is 200 ppm or better for most sizes and still is able to supply 1% tolerances as standard.
Touch-screen technology has become wildly popular, thanks to smart phones designed for nimble fingers. But most touch screens have a major drawback: you need to keep a close eye on the screen as you tap, to make sure that you hit the right virtual buttons.
Presented as having the highest power density of any device of its type, the XR Series of 2U programmable DC power supplies from Magna-Power can deliver voltages of up to 1000 Vdc and currents of up to 375 A.
Brocade Communications Systems Inc. is deepening its ties with a powerful ally, IBM Corp., forging a new distribution deal for Internet routers and switches at a time when bigger rival Cisco Systems Inc. is straining some of its old relationships.
President Obama once declared, “The United States government has no interest in running GM. We have no intention of running GM.” But recent developments could leave the federal government with majority ownership of GM. On February 17, GM submitted its “2009 – 2014 Restructuring Plan” to the Treasury Department. Highlights included
The ZigBee Alliance, a global ecosystem of companies creating standardized wireless solutions for use in energy management, commercial and consumer applications, today announced it will incorporate global IT standards from the Internet Engineering Task Force into its specification portfolio of low-power wireless networking standards.
