---|---|---|
Diameter | 1mm (0.04”) | 254mm (10”) |
Thickness | 0.08mm (0.003”) | 25.4mm (1”) |
Parts can be produced to the size ranges shown, but not in every combination of diameter and thickness dimensions.
Diameter | ±0.150mm |
Thickness | ±0.05mm |
Tighter mechanical tolerances are achievable but are dependent on the disc diameter and thickness.

Appropriate statistical methods ranging from AQL’s to 100% testing are used on electrical parameters in accordance with EN-50324-1. A brief summary is provided in hard copy and typically includes low field measurements of capacitance, tan delta and the main parameters used to determine piezoelectric activity. Procedures other than this can be negotiated, and additional data requirements (electronic format, sample quantity, etc) are available on request.
