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, PZT-82 series piezo material have the ultimate power handling capability.

Technical data:
