Affichant des performances fiables jusqu\u2019\u00e0 150\u00b0C, les nouveaux syst\u00e8mes TI de classe 0 que sont l\u2019isolateur ISO7741E-Q1 et l\u2019\u00e9metteur-r\u00e9cepteur TCAN1044EV-Q1 peuvent \u00eatre plac\u00e9s dans les zones des voitures hybrides et \u00e9lectriques susceptibles de monter \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es sans surco\u00fbt mat\u00e9riel ni complication du design.<\/p>\n
