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
