Piezo Ceramic Capacitor

Piezo Ceramic Capacitor uses the piezoelectric effect to realize transduction between electric and sound energy. It comprises a radiation head,Website:http://www.ceramic-metal-parts.com, electrode, cap, prestressed bolt, piezoelectric chip and an insulating tube. The piezoelectric transducer is widely used in ultrasonic cleaning machine and high-power industry  welding and drilling devices.High efficiency: high mechanical parameter Q, the transduction efficient between electricity and sound above 95%.High amplitude: the transducer strength is improved by fixing the high speed vibrator directly on the base of washing groove with bolt. Compare with a magnetic expansion vibrator, its amplitude can be improved above 50%.Good heat resistance: a large range of working temperature, low resonance impedance and heat productivity.Good construction: fastened by bolt, easy for assembling, high reliability.Model Piezoelectric Charge Coefficient d33(10-12C/N)Capacity CT（nF）Dielectric constant εT r3Resonant frequencyfs（kHz）Coupling Coefficientsk31（%）P-5A3-105×14×0.37-42081230013.637.0P-5B3-66.5×14×0.49-13.455055340021.537.2P-5B3-63.5×14.3×0.42-12.555049340022.532.9P-5B3-90×9×0.18-550135340015.938.0P-5B3-70×14.5×0.32-13.555089340020.436.7P-5B3-65×14.5×0.40-12.755062340022.035.6P-5C1-130×15.8×0.53-600154450011.037.0P-5C2-45×9×0.20-662063530031.130.2P-5A3-φ12×14202.3230017.165.0 (kp)P-51A-φ13×0.562801.6880015.460.0 (kp) Model Dimensions Coupling coefficients kp(%)Resonant frequency in parallel connection fp(kHz)6A-0.625±0.5×25±0.5×0.6±0.0235.089～926B-0.425±0.5×25±0.5×0.4±0.0225.092～956C1-0.525±0.5×25±0.5×0.49±0.0228.0
