Procurement Notes
Verify the specific suffix codes against the manufacturer's current datasheet to ensure compatibility with required mounting configurations and acoustic specifications. Confirm that the operating voltage range aligns with the system power supply. Check for any RoHS compliance certifications if required by your manufacturing standards. Ensure proper handling procedures are followed due to the sensitivity of piezoelectric elements to mechanical stress during installation.
Selection Notes
Select this component based on the requirement for a self-oscillating buzzer with surface mount capabilities. Consider the acoustic output requirements relative to the enclosure size and ambient noise levels. Evaluate the physical dimensions to ensure fit within the designated PCB area. Verify the polarity markings if the driving circuit requires specific DC connection orientation.
