Podzespoły  G3VM-31QR - miniaturowy przekaźnik półprzewodnikowy 

 

Firma Omron uruchomiła produkcję miniaturowego przekaźnika półprzewodnikowego, który zajmując na płytce drukowanej powierzchnię zaledwie 2,9 mm² może przewodzić prąd o natężeniu do 1,5 A. Nowy przekaźnik wykonano w oparciu o technologię MOSFET.

Zgodnie z intencją producenta, jest on przeznaczony przede wszystkim do sprzętu pomiarowego i testowego, w którym ważnym aspektem jest przestrzeń zajmowana przez obwody wejścia/wyjścia, co jednak nie wyklucza zastosowania przekaźnika również w innych aplikacjach.

Przekaźnik G3VM-31QR jest oferowany w obudowie S-VSON o wymiarach 2,0 mm×1,65 mm×1,45 mm. Zwarto w niej innowacyjny, 3-warstwowy chip półprzewodnikowy. W porównaniu do rozwiązań alternatywnych, nowy przekaźnik ma niższą rezystancję w stanie załączenia - wynosi ona 0,1 Ω.

Może przewodzić prąd o natężeniu do 1,5 A przy napięciu maksymalnym 30 V AC lub DC. Zakres temperatury otoczenia rozciąga się od -40 do +110°C. Napięcie przebicia pomiędzy wejściem a wyjściem wynosi 500 V, co jest wyjątkowe wśród tak małych przekaźników półprzewodnikowych.

ChipMOS Shanghai to grab backend orders for China homegrown 3D NAND chips

ChipMOS Technologies is expected to secure backend orders for 3D NAND flash chips developed by Yangtze River Storage Technology, according to market observers. YMTC, majority owned by Tsinghua Unigroup, has reportedly developed 32-layer 3D NAND flash chips in-house marking a new milestone and major technological breakthrough in China's memory-chip industry. Volume production of China's first homegrown memory chips is slated to kick off as early as the second or third quarter of 2018. ChipMOS Shanghai has already grabbed backend orders for NOR flash memory from Wuhan Xinxin Semiconductor Manufacturing, a wholly-owned subsidiary of YMTC, previous reports quoted industry sources as saying. więcej na: www.digitimes.com

STMicroelectronics recognized for leadership on environmental actions by CDP

STMicroelectronics has been identified as a worldwide leader in corporate sustainability, and awarded a position on this year’s “A” List for water and “A-” for climate change by CDP, the non-profit environmental disclosure platform. Among the 2,025 companies that were evaluated worldwide, the Water “A” List recognizes the top 10% of companies participating in the CDP’s water program, for their actions in the last reporting year to manage water more sustainably. ST is one of only three semiconductor manufacturers worldwide to be recognized. The Company’s “A-” score for climate change is also among the 22% highest scoring companies. więcej na: www.st.com

Tesla electric Semi's price is surprisingly competitive

When Tesla unveiled its Semi electric truck last week, everyone agreed that it looked cool, but some actual truckers weren't necessarily sold on its functionality. Most observers will be impressed with the pricing if it holds, though. Tesla has listed estimated price on its Semi website for the 300- and 500-mile versions of $150,000 and $180,000 respectively, less than some pundits predicted. The fancier Founders Series, with the top specs, will cost $200,000. Looking at the $180,000 model, it's still around $60,000 more than a diesel-powered semi truck. However, the Semi could cost around 20 percent less to run, Tesla estimates, putting savings over a million miles at around $250,000. więcej na: www.engadget.com
