Multilayered ceramic capacitor and mounting structure of circuit board having multilayered ceramic capacitor mounted thereon
摘要:
There is provided a multilayered ceramic capacitor, including a ceramic body, an active layer including a plurality of first and second internal electrodes alternately exposed through both end surfaces of the ceramic body while having the dielectric layer therebetween, to form capacitance; upper and lower cover layers formed above and below the active layer; first and second external electrodes covering both end surfaces of the ceramic body; a plurality of first and second dummy electrodes extended from the first and second external electrodes; and a plurality of piezoelectric members connecting the first internal electrode and the first dummy electrode or the second internal electrode and the second dummy electrode, inside the active layer, the piezoelectric members having a higher dielectric constant than the dielectric layer.
