Procurement Notes
Verify the specific ordering suffix and mechanical dimensions against the official datasheet before procurement. Confirm that the through-hole footprint matches the target PCB layout. Ensure the operating voltage and current ratings align with the driving circuit capabilities to prevent component damage or insufficient performance.
Selection Notes
Select this component when an electromagnetic buzzer with through-hole mounting is required. Consider the 2.048 kHz resonant frequency and 78 dBA sound pressure level for audibility requirements. Verify compatibility with the system's drive voltage and current limits. Evaluate space constraints relative to the physical dimensions provided in the specifications.
Part Context
This part belongs to the AT series of audio transducers from PUI Audio. The series includes various electromagnetic and piezoelectric options for different mounting styles and electrical characteristics. The AT-1220-TT-11-R specifically addresses needs for low-voltage, through-hole mounted magnetic buzzers.
Replacement Considerations
Check for direct substitutes within the AT series or other PUI Audio electromagnetic buzzers with similar resonant frequencies and mounting types. Verify mechanical fit and electrical parameters such as voltage and current ratings before substituting.
