3. Electrical And Acoustical Measuring Condition

Recommended Driving Circuit

Resonant frequency, 1/2 duty cycle. Square wave.Signal amplitude should be large enough tosaturate the transistor.

Recommended Setting

 

4.Frequency Response

3Vo-p 50% duty Square wave,10cm

 

5. Surface mounting condition

5.1 Reflow soldering

Recommendable reflow soldering condition is as follows.

 

Note:

(1) In automated mounting of the SMD sound transducers on PCB, any bending, expanding and pulling forces or shocks against the SMD sound transducers shall be kept minimum to prevent them from electrical failures and mechanical damages of the devices.
(2) In the reflow soldering, too high soldering temperatures and too large temperature Gradient such as rapid heating or cooling may cause electrical failures and mechanical damages of the devices.
