Y-TYPE FERRITE AND A FERRITE MOLDING PRODUCT MANUFACTURED BY USING THEREOF CAPABLE OF ACCOMPLISHING MINIATURIZATION AND BROADENING BANDS OF ELECTRONIC DEVICES IF THE FERRITE IS APPLIED AS MAGNETIC MATERIALS OF ALL KINDS OF ELECTRONIC DEVICES
Y-TYPE FERRITE AND A FERRITE MOLDING PRODUCT MANUFACTURED BY USING THEREOF CAPABLE OF ACCOMPLISHING MINIATURIZATION AND BROADENING BANDS OF ELECTRONIC DEVICES IF THE FERRITE IS APPLIED AS MAGNETIC MATERIALS OF ALL KINDS OF ELECTRONIC DEVICES
PURPOSE: A Y-type ferrite and a ferrite molding product manufactured by using thereof are provided to increase magnetic permeability and lower investment loss at high frequency bands which is higher than 1GHz.;CONSTITUTION: A Y-type ferrite is represented by chemical formula 1. The chemical formula 1 is same as follow: Ba2CoaZnbCucMndFe12O22. In the chemical formula 1, a, b, c, and d are positive numbers and satisfy following condition: 1.8 = a + b + c + d = 2.2. In frequency band of 1-3GHz, the magnetic permeability is 2 or greater. In frequency band of 1GHz, the magnetic permeability is 4-6, and in frequency band of 2.4GHz is 3.5-3.9. In frequency band of 1-3GHz, the investment loss is 1 or less. The ferrite molding product includes Y-shaped ferrite. The ferrite molding product has a film, a sheet, or a block shape.;COPYRIGHT KIPO 2012
