A dielectric ceramic and a capacitor comprising the dielectric ceramic are disclosed. The dielectric ceramic has a high dielectric constant that is stable over temperature, and has a small spontaneous polarization. The capacitor can reduce audible noise caused by an electrically induced strain in a power supply circuit.
