Designs with Piezo-ceramics
The applications for piezo-ceramic components and the materials precisely tuned to them are as varied as the options available for their design.

1) Reference values which may be higher or lower depending on customer specifications. It is not possible to combine extreme values. 2) In some resonant applications it has become standard practice to specify the resonance frequency (defined via the frequency constant) instead of a mechanical dimension. |
