| Abstract: | The vibration behaviour of piezoelectric ceramic resonators with thickness expansion mode is analyzed and its equivalent circuit is obtained. The formulas for resonant frequency, anti-resonant frequen-cy and parameters of the equivalent circuit with resonator size, dielectric constants, piezoelectric constants and elastic constants of resonator material are derived. Finally some properties and manufacture of the resonators are discussed. |
