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.
