Piezo Electric Ceramic Ring Transducer. Part Number: SMR1005T20111 Piezoelectric Ceramic Ring with Silver electrodes on both sides.  Piezo Material: SM111 Dimensions: OD 10 x ID 5 x Th 2mm Resonant frequency fr: 142 KHz±4 KHz Electromechanical coupling coefficient Kr:

Resonant Mode: Radial mode by impedance analyzer. Resonant impedance Zm: ≤20 Ω Static capacitance Cs: 350pF±15%@1kHz Test Condition: 23±3 °C 40~70% R.H. fr, Zm, Kp => Radial mode by impedance analyzer. Cs => LCR meter at 1KHz 1Vrms Drawings: SMR1005T20111, Applications: Bolt-clamped ultrasonic transducer, Ultrasonic Sensor, Vibration Sensor, Pressure, sensor, Vibration generation, Biodiesel mixing transducer, Piezo expansion sensor, compression sensor, Piezo Welding, Tonpilz and others. Notes: Keff = ≥35%. Keff is calculated by the formula, ((fa2-fr2)/fa2), and fa is the anti-resonant frequency of the hoop mode. Old Part Number: SMR1005T20SMQA, SMD1005T20
