Piezoelectric Ceramic Ring with Silver electrodes on both sides.

Piezo Material: SM111
Dimensions: OD 15 x ID 8.5 x Th 0.7mm
Resonant frequency fr: 91KHz ± 3KHz
Electromechanical coupling coefficient Keff: ≥36%     
Resonant Mode: Hoop mode vibration
Resonant impedance Zm: ≤12 Ω
Static capacitance Cs: 2100pF±15%@1KHz
Test Condition: 25±3 °C 40~70% R.H.
fr, Zm, Kp => Hoop mode vibration
Cs => LCR meter at 1KHz 1Vrms

Applications: Bolt-clamped ultrasonic transducer, Ultrasonic Sensor, Vibration Sensor, Pressure sensor, Vibration generation, Biodiesel mixing transducer, Piezo expansion sensor, compression sensor, Piezo Welding, Tonpilz Transducer and others. and others.
Notes: Keff is calculated by the formula, √((fa2-fr2)/fa2), and fa is the anti-resonant frequency of the hoop mode.
