    Piezoelectric ceramic disc  

    Quick shipments

    High power

    low dielectric loss

    wrapped arround electrode available

     

    Application: ultrasonic slimming transducer, 

    Material:  PZT-82 (hard PZT, equal to P-8) or PBaS-4(hard PZT, high dielectric constant 1900)

     

    This material range is used in high power applications, even though its piezoelectric activity level is slightly lower than PZT-4 series types. With an extremely high mechanical quality factor and extremely low loss factor.
