Abstract

a. Ferrite. b. Ce ferrite de zinc et de manganèse à perméabilité élevée ou moyenne, à faibles pertes et contenant du calcium, a un coefficient de température de la perméabilité initiale pratiquement constant dans une plage de températures étendue. Il est préparé en mélangeant 49 à 55 % en mole de Fe2O3 dont 0,2 à 5% en mole de SnO2 ou de TiO2 ainsi que le pourcentage molaire restant de MnO et de ZnO à de faibles quantités de CaO et surtout de CoO. c. Industrie électronique.at. Ferrite. b. This high or medium permeability, low loss, calcium-containing zinc manganese ferrite has a substantially constant temperature coefficient of initial permeability over a wide temperature range. It is prepared by mixing 49 to 55 mol% of Fe2O3 including 0.2 to 5 mol% of SnO2 or TiO2 as well as the remaining molar percentage of MnO and ZnO with small amounts of CaO and especially CoO. vs. Electronics industry.
