Podzespoły G3VM-61VY2 i G3VM-351VY - tanie przekaźniki MOSFET
Do oferty Omron Electronic Components Europe wchodzą dwa nowe przekaźniki półprzewodnikowe zamykane w obudowach SOP-4 - G3VM-61VY2 i G3VM-351VY. Umożliwiają łączenie 60 V/0,5 A (-61VY2) i 350 V/110 mA (-351VY).
Są to podzespoły zrealizowane w technologii MOSFET, mające lepsze parametry od poprzednich wersji. Oba przekaźniki zapewniają wytrzymałość dielektryczną między wejściami i wyjściami na poziomie 3,75 kV. Przekaźnik G3VM-61VY2 może przełączać prąd o natężeniu do 500 mA przy rezystancji wewnętrznej wynoszącej jedynie 2 Ω. Z kolei, przekaźnik G3VM-351VY charakteryzuje się krótszym czasem wyłączania, wynoszącym typowo 0,1 ms, a maksymalnie 0,5 ms. Dodatkowo, rozszerzono zakres dopuszczalnej temperatury pracy do -40...+110°C.

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

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
