发明名称 DIELECTRIC CERAMIC COMPOSITION AND LAMINATED CERAMIC CAPACITOR
摘要 <p>The present invention provides a dielectric ceramic composition, which is, in addition to having superior resistance to reduction during firing, superior capacitance temperature characteristics after firing and superior dielectric characteristics, also demonstrates an enhanced lifetime for insulation resistance. The present invention is a dielectric ceramic composition comprising 0.18 to 0.5 part by weight of Yb 2 O 3 , 0.6 to 1.5 parts by weight of MgO, 0.4 to 1.5 parts by weight of CaSiO 3 , 0.02 to 0.2 part by weight of WO 3 , 0.1 to 0.4 part by weight of MnCO 3 and 0.02 to 0.2 part by weight of MoO 3 based on 100 parts by weight of (BaO) m ·TiO 2 (wherein, m is from 0.990 to 0.995).</p>
