Piezoceramic BBP4RG-28X9X0P3

Product overview
BBP4RG-28X9X0P3 is an ultra-thin piezoelectric ring (PZT-4) designed for thickness-mode ultrasonic sensor evaluation. It is suitable for prototype testing and integration where limited axial space and high-frequency response are required. For reliable selection, evaluate target frequency, geometry, electrode design, poling direction, drive conditions, mounting space and operating environment.
