Typical soft PZT characteristics include:

• Wide range of frequencies in transmit and receive (sub-audible, audible, ultrasonic)
• High output, low drive material
• High frequency, fast response time
• High sensitivity for active or passive use
• Ability to use with low voltage or high voltage drive circuits
• Good mechanical and acoustic coupling
• Wide variety of shapes and sizes that can be customized to meet specific requirements and applications
• Wide variety of compositions that can be selected to meet specific requirements and applications
• Quality of each PZT component is ensured by a rigorous testing regimen. Characteristics such as frequency, capacitance, dissipation, coupling, d33 and mechanical properties are measured and verified against our / customer provided specifications.
