    摘要: A glass frit for dielectrics, a dielectric ceramic composition, a multilayer ceramic capacitor, and a method for manufacturing the same are disclosed. The glass frit has a composition represented by the formula aSiO2-bB2O3-cLi2O-dK2O-eCaO-fAl2O3-gTiO2-hZrO2, wherein the ratio of components satisfies the conditions of 20≦a≦35, 20≦b≦35, 20≦c≦30, 3≦d≦5, 2≦e≦12, 2≦f≦10, 1≦g≦12 and 1≦h≦7 in terms of mol % where a+b+c+d+e+f+g+h=100. The dielectric ceramic composition comprises 100 parts by weight of (Ca1-xRx)(Zr1-yTiy)O3, 0.5˜2.5 parts by weight of the glass frit, and 1.0˜5.0 parts by weight of a Mn compound. Additionally, the multilayer ceramic capacitor, and the method for manufacturing the same also use the glass frit having the above composition. The ratio of tetracoordinate boron to tricoordinate boron is increased in a lithium borosilicate glass, thereby enhancing structural property, and the components of Al2O3, TiO2 and ZrO2, enhance acid resistance.

    摘要: Disclosed herein is a multilayer type power inductor including: a plurality of body layers including internal electrodes and having magnetic material layers stacked therein; and a plurality of gap layers, wherein the gap layer has an asymmetrical structure. In the multilayer type power inductor, portions that are in contact with the body layers have, a non-porous structure, which is a dense structure, and portions that are not in contact with the body layers have a porous structure, such that the gap layer has the asymmetrical structure. Therefore, a magnetic flux propagation path in a coil is dispersed to suppress magnetization at a high current, thereby making it possible to improve a change in inductance (L) value according to the application of current.
