Podzespoły  LF EDLCs - nowe superkondensatory o wydłużonym czasie eksploatacji 

 

Firma Panasonic poinformowała o wprowadzeniu do produkcji superkondensatorów dwuwarstwowych z rodziny "LF".

Charakteryzują się one małą rezystancją szeregową, niewielkim prądem upływu oraz parametrem MTBF wynoszącym co najmniej 6 tys. godzin. Aktualnie jest to najdłuższy czas MTBF wśród podobnych produktów. Napięcie znamionowe jest równe 5,5 V, pojemność 1 F, a zakres temperatury otoczenia -40…+85°C. Parametry są zoptymalizowane do zastosowania kondensatorów w inteligentnych systemach pomiarowych używanych w Europie. Świetnie nadają się np. do użycia jako awaryjne źródło zasilania mikroprocesora czy układu zegara RTC.

Kondensatory Panasonica z serii LF mają znacznie większą pojemność niż zbliżone wymiarami kondensatory elektrolityczne (nawet do 1000 razy więcej). Charakteryzują się też dużą odpornością na prąd ładowania i rozładowania o podwyższonym natężeniu - jest on porównywalny z uzyskiwanym z baterii stosowanych do zasilania pomocniczego. Parametry kondensatorów są gwarantowane dla 500 tys. cykli gwałtownego ładowania/rozładowania. Dostępne są w kompaktowej, cylindrycznej obudowie o średnicy 21,5 mm i wysokości 10 mm.

Amazon launches biggest wind farm yet

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

Apple plans on selling lower priced models with iPhone X features

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 partner on voice recognition tech

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 reveals compact contactless module with boostedNFC technology

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

Graphics card vendors upbeat about crytocurrency mining

As the values for some major cryptocurrencies continue rising and prolonging related graphics card demand, graphics card vendors, including Asustek Computer who was originally conservative about the mining trend, have been expanding their orders for Nvidia and AMD GPUs, according to sources from the upstream supply chain. Gigabyte Technology and MSI, TUL, Colorful and Galaxy Microsystems have all been aggressive about the cryptocurrency opportunity since the mining trend emerged, and they have seen dramatic growths in related businesses. Asustek only started to see benefits from the segmnet in the third quarter. Because of the quickly subsided cryptocurrency mining hype in 2013, some graphics card players were originally conservative about the development in 2017. więcej na: www.digitimes.com
