Multi-layer ceramic capacitor

A multi-layer ceramic capacitor includes dielectric ceramic layers (11) extending between internal electrode layers (12). The dielectric ceramics mainly include an oxide containing a component A and a component B. Component A is selected from a group I of lead (Pb), calcium (Ca), strontium (Sr), and...

Beschreibung
Zusammenfassung:	A multi-layer ceramic capacitor includes dielectric ceramic layers (11) extending between internal electrode layers (12). The dielectric ceramics mainly include an oxide containing a component A and a component B. Component A is selected from a group I of lead (Pb), calcium (Ca), strontium (Sr), and barium (Ba), and includes lead at least, component B is selected from a group II of magnesium (Mg), nickel (Ni), titanium (Ti), zirconium (Zr), zinc (Zn), niobium (Nb), tantalum (Ta) and tungsten (W) and includes at least two of these substances. The ratio of the total mol value of the substances in A to the total mol value of the substances in B is between 0.985 and 1.110 and the dielectric further contains about 0.03 to 0.65 wt% copper in terms of Cu2O content.
