Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix to ensure the correct acoustic and electrical characteristics match the design requirements. Confirm that the surface mount footprint aligns with the PCB layout specifications. Check the datasheet for detailed mechanical dimensions and thermal handling limits to ensure reliable operation within the intended environmental conditions.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-output surface mount buzzer is required for space-constrained designs. Consider the 4kHz resonant frequency for optimal audibility in noisy environments. Ensure the driving circuit can provide the necessary voltage swing up to 30VAC without exceeding the 12mA current limit. Evaluate the 95dBA SPL requirement against regulatory noise standards for the target application.

Alarms, Buzzers, And Sirens Part Context

This part belongs to PUI Audio's SMT series of piezoelectric transducers, which are engineered for high-volume manufacturing integration. The series offers various resonant frequencies and sound pressure levels to accommodate different acoustic signaling needs. These components are widely used in electronics where reliable, long-lasting audible alerts are essential for user interaction or system feedback.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other SMT series parts from PUI Audio for alternative resonant frequencies or SPL ratings. Verify mechanical compatibility before substituting with generic surface mount buzzers, as pad layouts and height restrictions may differ significantly between manufacturers.
