High power piezo disc for ultrasonic transducer OD28x1MHz

High power piezo disc for ultrasonic transducer OD28x1MHz

Basic Info

    Model No.: OD28*1MHz

Product Description

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:

Dimensions: diameter 28mm, thickness 2mm according to frequency 1MHz

Thickness Frequency(Ft) 1MHz ± 5%
Statics Capacity (pF) 2500pF ± 12.5%
Dielectric loss(tgδ)(1v,KHz) ≤0.3%
