Podzespoły MG12600WB-BR2MM - półmostkowe moduły IGBT 1200 V/600 A
Firma Littelfuse wprowadziła do oferty serię półmostkowych modułów IGBT MG12600WB-BR2MM przeznaczonych do zastosowania w sterownikach napędów przemysłowych, falownikach, spawarkach i zasilaczach UPS o dużej mocy. Moduły mają napięcie przebicia 1200 V i większy, dopuszczalny prąd obciążenia w porównaniu do wcześniej oferowanych - 600 A zamiast 450 A.
Jednocześnie są z nimi kompatybilne pod względem sterowania i wyprowadzeń, dzięki czemu mogą być stosowane zamiennie w razie potrzeby zapewnienia większej mocy zasilania dostarczanej do obciążenia. Moduły z serii MG12600WB-BR2MM są oferowane w obudowie o wymiarach 152 mm×62 mm×17 mm z terminalami śrubowymi o konfiguracji WB.
W modułach zastosowano technologię Trench-gate Field Stop IGBT zapewniającą małe straty wskutek przewodzenia i przełączania. Oprócz tego zapewnia ona małe napięcie nasycenia i dodatni współczynnik temperaturowy, co ułatwia równoległe łączenie modułów.

Taiwan-based LED firms, in view of tight supply of AMOLED smartphone panels and increasing competition in the LED backlighting segment from China-based makers, are ready adopt mini LEDs for TV and smartphone backlighting applications and fine pixel pitch displays, according to industry sources. With sizes of about 100 micrometers, mini LED chip poduction does not need mass transfer, a technological bottleneck for micro LEDs, the sources said. To cope with tight supply of AMOLED panels, Android smartphone vendors, especially China-based ones, are looking to adopt mini LEDs for backlighting to boost competitiveness against AMOLED-equipped devices, the sources noted. więcej na: www.digitimes.com

Amazon announced that its largest wind farm yet - Amazon Wind Farm Texas - is now up and running, adding more than 1,000,000 MWh of clean energy to the grid each year. Amazon has launched 18 wind and solar projects across the U.S., with over 35 more to come. Together, these projects will generate enough clean energy to power over 330,000 homes annually. These projects also support hundreds of jobs and provide tens of millions of dollars of investment in local communities across the country. Amazon Wind Farm Texas includes more than 100 turbines - each over 300 feet tall with a rotor diameter more than twice the wingspan of a Boeing 787. więcej na: www.businesswire.com

According to a report published in China, Apple will be using some of the technology found in this year's Apple iPhone X on next year's models that are rumored to have code names of Lisbon and Hangzhou. The report says that Apple is concerned about its market share in China, and believes that by offering many iPhone X features in a lower priced phone, it can help it recapture market share in the country. Another website in Japan, Macotakara, expects the lower-end model would get a 10,000 yen ($90 USD) hair cut from this year's pricing. Next year's phones are all expected to include an OLED display, and the TrueDepth Camera. Face ID will also replace Touch ID on all 2018 Phone models next year. więcej na: www.phonearena.com

Intel and Amazon are partnering to combine the former's silicon and smarts with the latter's Alexa voice platform. The chipmaker has introduced the Intel Speech Enabling Developer Kit to provide a "complete audio front-end solution for far-field voice control". The idea is that Intel has done the hard work of designing the mic arrays and voice systems and that all developers will need to do is write applications for them. It offers algorithms for echo cancellation and beam forming, wake words, an 8-mic array and the company's dual digital signal processor. The development kit is up for pre-order starting today for $399. And while that might be a little too expensive for a hobbyist developer, it isn't exorbitantly priced like some game console development kits. więcej na: newsroom.intel.com

STMicroelectronics is delivering the technology for easy and secure contactless transactions using the ever more popular wristbands or fashionwear like watches or jewelry. The market-unique ST53G System-in-Package solution combines the Company’s industry-leading expertise in Near Field Communication and secure-transaction chips. As consumers become increasingly comfortable with making secure transactions using their smart devices, traditional card manufacturers want to extend their offers into contactless wearable products for uses such as payments, ticketing, and access control. These can be difficult to implement within tight size and cost constraints, because conventional separate NFC-radio and security chips demand extra space and complicate design. więcej na: www.st.com
