Procurement Notes
Verify the specific package type and terminal configuration against the official datasheet before procurement. Confirm that the operating voltage range aligns with the system design requirements to ensure proper functionality. Check for any specific handling or storage conditions mandated by the manufacturer to maintain component integrity during assembly.
Selection Notes
Select this component when a through-hole electromagnetic buzzer is required for applications needing a 2.73 kHz tone. Ensure the PCB layout accommodates the 9 mm x 9 mm footprint and 4.5 mm height constraints. Verify that the driving circuit can provide the necessary 90 mA current at the specified peak-to-peak voltage without exceeding thermal limits.
Part Context
This part belongs to the PUI Audio series of audio indicators and buzzers. It utilizes electromagnetic technology distinct from piezoelectric alternatives. The through-hole format distinguishes it from surface-mount variants within the manufacturer's portfolio, offering mechanical stability for specific enclosure designs.
Replacement Considerations
Cross-reference with other PUI Audio through-hole electromagnetic buzzers sharing the 2.73 kHz frequency and similar physical dimensions. Verify electrical compatibility regarding voltage and current ratings before substituting.
