                   *Guideline values only. Parts with larger or smaller
                   dimensions may be produced.
     We provide piezo ceramic elements manufactured to the industry tolerance values listed here. We can prepare elements to tighter tolerances on request. Items also are available "as fired" (no OD, ID, length or width machining), when dimensional requirements are not critical.
              Please be specific when requesting parts, tolerances, or electrode patterns. Provide drawings or sketches for parts or electrode patterns, and include ID tolerance if requesting rings or cylinders (tubes). For custom electrical leads, please specify AWG and length and provide a drawing showing the desired locations.
 Standard tolerances for electrical / piezoelectric characteristics:          
frequency: ±5% (to ±0.5% on request)
capacitance: ±15%
d33 value: ±20%
