Designs with Piezo-ceramics

Versatile Design for Piezo-ceramic Components

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.
Example: Disc made of SONOX® P4 Ø 20 mm ± 0.2 mm x 1 MHz ± 10 %. 1 MHz is the resonance frequency of the thickness-mode oscillation of the disc, corresponding to a disc thickness of approximately 1 mm.
