    1. Dimensions

    Unit: mm

     

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

    1. Electrical And Acoustical Measuring Condition

    Recommended setting
         

    1. Frequency Response

     

    1. 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.

    1. Reliability Test

    After any following tests the part shall meet specifications without any degradation in
           appearance and performance except SPL. SPL shall not deviate more than -10 dB
           from the initial value

      1. Ordinary Temperature Life Test

    The part shall be subjected to 96 hours at 25±10℃. Input rated voltage
           Resonant frequency, 1/2 duty Square wave.
           6.2 High Temperature Test
           The part shall be capable of with standing a storage temperature of +80℃ for 96 hours.
           6.3 Low Temperature Test 
           The part shall be capable of with standing a storage temperature of -30℃ for 96 hours.

      1. Humidity Test

    Temperature:+40℃±3℃   Relative Humidity:90%~95% Duration: 48 hours
           and expose to room temperature for 6 hours

      1. Temperature Shock Test

    Temperature:60℃ /1hour→ 25℃/3hours→-20℃/1hour→ 25℃/3hours (1cycle)
           Total cycle: 10 cycles

      1. Drop Test

    Standard Packaging From 75cm(Drop on hard wood or board of 5cm thick,
           three sides, six plain.)

      1. Vibration Test

    Vibration:1000cycles /min. Amplitude:1.5mm, Duration: 1 hour in each 3 axes

      1. Reflow Test

    Use recommendable reflow soldering condition (as shown in 5.1)
           (1) No abnormality should be found after reflow
           (2) Good soldering to meet soldering requirements

     

    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.
