Instructions for Use

1. Power Supply:

   • Ensure the supply voltage is within the operating range of 3V to 5V.
   • Connect the positive terminal of the power supply to the "+" pad and the negative terminal to the "-" pad.

2. Mounting:

   • Place the YG902C2 on the PCB with the solder pads aligned.
   • Solder the pads securely, ensuring good electrical contact.

3. Operation:

   • Apply the appropriate voltage to activate the buzzer.
   • The buzzer will emit a sound at its resonant frequency of 4kHz, with a typical sound pressure level of 85dB at 10cm.

4. Environmental Considerations:

   • Operate the buzzer within the specified temperature range (-20掳C to +70掳C).
   • Store the buzzer in a dry environment within the storage temperature range (-30掳C to +80掳C).

5. Handling:

   • Handle the buzzer with care to avoid damage.
   • Do not apply excessive force or torque to the terminals during soldering.

6. Testing:

   • Test the buzzer by applying the operating voltage and verifying the sound output.
   • Use an oscilloscope or multimeter to check for proper electrical connections and impedance.

7. Maintenance:

   • No special maintenance is required under normal operating conditions.
   • If the buzzer fails to operate, check the power supply and connections for any issues.
