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.

Samsung, Foxconn to back cable-free phone tech

A startup backed by Tony Fadell, one of the fathers of the Apple iPod, plans to announce it is working with Samsung Electronics Co Ltd, Foxconn and others on a new way for mobile phones to transfer large amounts of data without using wires or WiFi connections. Chief Executive Eric Almgren said his Campbell, Calif.-based company called Keyssa has raised more than $100 million from Fadell and the venture arms of Samsung and Intel Corp, among others. The company’s “kiss” technology allows two computing devices to be held near each other and transfer large files such as movies in just a few seconds. więcej na: www.reuters.com

NVIDIA to increase 12nm production for next-gen Volta GPU

AMD just released their Radeon RX Vega family of graphics cards while NVIDIA has increased production with TSMC of their new 12nm Volta based GPU’s. NVIDIA’s new Volta GPU’s will feature a 12nm process which both TSMC and NVIDIA have been ramping up together for a release of the new GPU’s in hopefully early 2018. Just recently the CEO of of NVIDIA Jen-Hsun Huang was talking to investors about NVIDIA’s next-gen GPU and he replied saying the gamers shouldn’t be expecting Volta-based GPU GeForce card until end of 2017 or perhaps even early 2018. więcej na: deathrattlesports.com

Candy cane supercapacitor could enable fast charging of mobile phones

Supercapacitors promise recharging of phones and other devices in seconds and minutes as opposed to hours for batteries. But current technologies are not usually flexible, have insufficient capacities, and for many their performance quickly degrades with charging cycles. Researchers at QMUL and the University of Cambridge have found a way to improve all three problems in one stroke. Their prototyped polymer electrode, which resembles a candy cane usually hung on a Christmas tree, achieves energy storage close to the theoretical limit, but also demonstrates flexibility and resilience to charge/discharge cycling. więcej na: phys.org
