Note:

As this product is not protected from foreign material entering, please make sure that any foreign materials (e.g. magnetic powder, washing solvent, flux, corrosive gas) do not enter this product in your production processes. The functional degradation (e.g. SPL down) may occur if foreign material enter it.

3. Electrical And Acoustical Measuring Condition

3.1 Recommended Driving Circuit

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

4. 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.
