Abstract: A magnetic dielectric resin composition, and a prepreg and a copper clad laminate comprising same. The magnetic dielectric resin composition comprises a resin and a magnetic filler. The absolute value of the temperature drift coefficient of the magnetic filler under the conditions of −55° C. to 150° C. is 0-1000 ppm/° C. Preparation raw materials of the magnetic filler comprise a combination of iron oxide and a metal oxide. By means of mutual synergy of the resin and the specific magnetic filler, and on the premise of ensuring good dielectric properties, the magnetic dielectric resin composition has a high magnetic permeability, a low magnetic loss, and a proper cut-off frequency, and can also reduce a temperature drift coefficient and improve stability. The copper clad laminate comprising the magnetic dielectric resin composition has a high relative magnetic permeability, a low magnetic loss, a low temperature drift coefficient, and a superior thermal stability, and can fully satisfy application requirements for copper clad laminate in the preparation of high-performance and miniaturized electronic products.
