1.Technical Parameter Measuring condition
Part shall be measured under a condition (Temperature: 5～35℃,  Humidity: 45%～85%R.H., Atmospheric pressure: 860 ～1060hPa)  unless the standard condition (Temperature: 25±3℃, Humidity:  60±10%R.H. Atmospheric pressure: 860 ～1060hPa) is regulated to  measure. 

2.Dimensions Unit: mm          

*Unit: mm; Tolerance: ±0.3mm Except Specified
*Housing Material: Black LCP 
*Terminal plate: 2 soldering pads, tin Plating Brass 

4.Frequency Response

3Vp-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.

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.
