PURPOSE : An NiZnCu based ferrite composition and a multilayered chip component using the same are provided to increase density, a Q value, and magnetization saturation by using ferrite compositions. CONSTITUTION : An NiZnCu based ferrite composition includes rare earth metal. The rare earth metal is selected from Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. The rare earth metal is 0.01 to 2.0 weight%% of the total composition. A ferrite composition is plasticized below 880 to 920 degrees centigrade. COPYRIGHT KIPO 2012
