Abstract
A dielectric composition for a multilayered ceramic capacitor is provided, the multilayered ceramic capacitor includes the same, and a manufacturing method for the capacitor is also provided. The dielectric composition for a multilayered ceramic capacitor includes a barium-based compound, gadolinium oxide (Gd2O3), manganese oxide (Mn3O4), and magnesium carbonate (MgCO3). Accordingly, the dielectric composition is excellent in performance as well as reliability.
Claims6
