Abstract

A ceramic material for a multilayer ceramic capacitor has a capacitance variation from −17 percent to +15 percent at a temperature ranging from −55° C. to 200° C., and has a dielectric loss less than 1% at a temperature ranging from 90° C. to 200° C. The ceramic material includes a base component consisting of a barium titanate and a sodium bismuth titanate, and a manganese dopant in an amount not greater than 0.05 mole percent based on total moles of the base component.
