A material that can store energy when a voltage is applied causing electric polarization is called dielectric property. Having especially high dielectric constant and being an excellent insulator, dielectric ceramics are widely used in capacitors. A capacitor works as a dam in an electric circuit and is the most frequently used component in circuits. Ferroelectric barium titanate-based chip monolithic ceramic capacitors are very compact, have high capacitance, no lead terminals so they are suitable for surface mounting, and therefore widely used in electronic circuits. Murata has an unrivaled record in the technology and quality of its chip monolithic ceramic capacitors. Furthermore, in wireless communications, where the dielectric property of reducing the high frequency electromagnetic wavelength is applied, dielectric filters and antennas are key devices for mobile phones.
