Due to Covid-19 virus there are fewer airplanes flying International routes. Thus, there is a HUGE delay on International orders shipped by USPS.
Currently there are no delays on International orders shipped by FedEx, UPS or DHL and you can select collect freight when placing your order.

Piezo Electric Disc 50x3mm R 45 KHz

Availability: 241 in stock
/2 Pcs Set
Condition: New

Part Number: SMD50T30F45R

Piezo Electric Ceramic Disc Transducer. Both electrodes on one side (R configuration).  Radial mode vibration application

Piezo Material: SM111
Dimensions: 50mm diameter x 3mm thickness
Resonant frequency fr: 44 KHz±3 KHz     
Electromechanical coupling coefficient Kp:≥60%
Resonant impedance Zm: ≤8 Ω
Static capacitance Cs: 7200pF±15%@1kHz
Test Condition: 23±3 °C 40~70% R.H.
fr, Zm, Kp => Radial mode vibration application
Cs => LCR meter at 1KHz 1Vrms

Applications: Ultrasonic Sensor, Vibration Sensor, Wall thickness sensor, Material stress sensor, Pressure sensor, Vibration generation, Energy/Electricity harvesting, Biodiesel mixing transducer, Fish finder transducer and others.
Notes: The max voltage that this transducer can withstand is 1050V, but the most important issue is the maximum power allowed which is 55W. If input voltage is increased up to the maximum value, the power should always be kept below the max power. Of course the maximum power will be dependent on the bonding job. So the operation voltage we suggest is 280V. The wrap around electrode has the negative polarity.
