Low harmonic distortion ceramic-multilayer capacitor

Third-harmonic-wave distortion (THD) of high-K ceramic multilayer capacitors is usually as high as -60 dB due to the nonlinear behavior of ferroelectric BaTiO/sub 3/-based materials. A recently developed SrTiO/sub 3/-based material makes possible a multilayer capacitor with less wave distortion. THDs of better than -90 dB have been obtained over a wide range of applied AC voltages. This dielectric has a dielectric constant of 1300 and is fired at 1140 degrees C. Performance data and specific applications are reported. >
