Introduced as the first model of Sonitron's piezoceramic speakers, the SCS-series are still being used for numerous applications. Good sound quality and limited distortion guarantee a clear reproduction of multiple tones. The piezo speaker has 60 % more net sound output per membrane surface than the electro-dynamic speaker in the function of the average current drain and average sound pressure level.Download sheet Download 3D model

Theoretical the main impedance of the piezo speakers is a capacitive reactance and follows an asymptotic function.
The typical practical impedance values (+/-20%) for frequencies of 100 Hz up to 20kHz of our speakers are as follows:
|Capacitance||20 nF||37 nF||66 nF|
|Z (0.1kHz)||79577 ohm||43000 ohm||24114 ohm|
|Z (1 kHz)||7957 ohm||4300 ohm||2411 ohm|
|Z (2 kHz)||3978 ohm||2150 ohm||1205 ohm|
|Z (5 kHz)||1591 ohm||860 ohm||482 ohm|
|Z (10 kHz)||795 ohm||430 ohm||241 ohm|
|Z (15 kHz)||530 ohm||286 ohm||161 ohm|
|Z (20 kHz)||397 ohm||215 ohm||121 ohm|
