Instructions for Use:

1. Power Supply:

   • Connect the positive terminal of the buzzer to the positive supply voltage (3V to 5V DC).
   • Connect the negative terminal to ground.

2. Frequency Control:

   • The buzzer is designed to operate at its resonant frequency of 4kHz for optimal performance.
   • For custom frequencies, use an external oscillator or signal generator to drive the buzzer.

3. Mounting:

   • Ensure the buzzer is securely mounted on the PCB using the provided solder pads.
   • Avoid applying excessive force during soldering to prevent damage to the component.

4. Environmental Conditions:

   • Operate the buzzer within the specified temperature range (-20掳C to +70掳C) to ensure reliable performance.
   • Store the buzzer in a dry environment within the storage temperature range (-40掳C to +85掳C).

5. Handling:

   • Handle the buzzer with care to avoid physical damage.
   • Follow standard ESD (Electrostatic Discharge) precautions when handling the component.

6. Testing:

   • Test the buzzer by applying the recommended operating voltage and verifying the sound output.
   • Use a multimeter to check the impedance at the resonant frequency if necessary.

7. Disposal:

   • Dispose of the buzzer in accordance with local environmental regulations.
   • The buzzer is RoHS compliant, ensuring it meets environmental standards for hazardous substances.
