Podzespoły  MDmesh K5 - 900-woltowe MOSFETy do przetwornic o bardzo dużej sprawności 


Tranzystory MOSFET MDmesh K5 firmy STMicroelectronics umożliwiają uzyskanie większej mocy wyjściowej i sprawności przy zmniejszeniu wymiarów gotowej przetwornicy.

Napięcie przebicia wynoszące 900 V DC daje szorki obszar aplikacji, a rezystancja RDS(on) mniejsza niż 100 mΩ jest najmniejszą wśród aktualnie dostępnych w handlu tranzystorów w obudowach DPAK.

Niewielki ładunek bramki umożliwia uzyskanie krótkiego czasu przełączania. Tranzystory MDmesh K5 są przeznaczone do przetwornic o mocy od 35 do 200 W. Ich parametry pozwalają na wykonywanie przełączników ZVS o minimalnych stratach mocy w półmostkowych, rezonansowych przetwornicach LLC.

Korea develops super-fast Wi-Fi

A state-run Korean institute has developed super-fast Wi-Fi network technology. The Electronics and Telecommunications Research Institute announced it successfully tested the technology called "mobile hotspot network."
