发明名称 Dielectric ceramic composition with dielectric core-shell particles and electronic device
摘要 <p>A multilayer ceramic capacitor comprising a capacitor element body: wherein dielectric layers composed of a dielectric ceramic composition and internal electrode layers are alternately stacked; the dielectric ceramic composition comprises a plurality of dielectric particles each having a shell, wherein subcomponents are dispersed in a main component, formed around a core substantially composed of the main component; and a difference of the maximum thickness and the minimum thickness of the shell in the dielectric particles having an average particle diameter is controlled to be 6 to 60% of a radius of the dielectric particles; wherein a high permittivity and preferable temperature characteristic are obtained and TC bias characteristics are improved, is provided.</p>
