Procurement Notes
Verify the specific suffix '4' against official datasheets to confirm exact electrical tolerances and mechanical variations compared to standard variants. Ensure compatibility with existing PCB footprints and drive circuits designed for 12 VDC operation. Confirm RoHS compliance status through manufacturer documentation prior to final procurement decisions.
Selection Notes
Select this component when a high-intensity 95 dBA audible alert is required within a compact 23.8 mm form factor. The 12 VDC rating suits systems with stable DC power supplies. Consider the through-hole mounting style if mechanical vibration resistance is prioritized over surface area constraints on the printed circuit board.
Part Context
This part belongs to the AI series of audio indicators from PUI Audio, specializing in piezoelectric buzzers. The series offers various voltage and frequency options for diverse signaling needs. This specific model provides a balance of volume and size suitable for general-purpose electronic applications requiring clear auditory feedback.
Replacement Considerations
