Input rated voltage Resonant frequency, 1/2 duty Square wave. 2.2 High Temperature Test The part shall be capable of with standing a storage temperature of +85℃ for 96 hours. 2.3 Low Temperature Test The part shall be capable of with standing a storage temperature of -40℃ for 96 hours. 2.4 Humidity Test Temperature:+40℃±3℃ Relative Humidity:90%~95% Duration: 48 hours and expose to room temperature for 6 hours 2.5 Temperature Shock Test Temperature:70℃ /1hour→ 25℃/3hours→-30℃/1hour→ 25℃/3hours (1cycle) Total cycle: 10 cycles 2.6 Drop Test Standard Packaging From 1.2m(Drop on hard wood or board of 5cm thick, three sides, six plain.) 2.7 Vibration Test Vibration:1000cycles /min. Amplitude:1.5mm, Duration: 1 hour in each 3 axes 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.
| 3.2 Recommended Setting
|
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. |
