Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical dimensions prior to integration. Ensure PCB layout accommodates the side-firing port orientation and surface mount pad configuration. Confirm compliance with relevant environmental directives such as RoHS requirements for the target market.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, high-intensity audible signal is required in space-constrained designs. The side-firing characteristic allows for flexible enclosure mounting orientations. Consider the 80 mA current draw and 3V drive requirement when designing the driving circuitry to ensure adequate power supply capacity.

Alarms, Buzzers, And Sirens Part Context

This part belongs to PUI Audio's SMT series of surface mount transducers. The series is characterized by small footprints and electromagnetic actuation mechanisms. The SMT-1427-S-7-R specifically targets applications needing reliable audio feedback in harsh environments due to its extended temperature rating.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other side-firing surface mount transducers from PUI Audio with similar frequency and SPL ratings, such as the SMT-0727-S-R or SMT-1427-S-6-R, provided mechanical and electrical parameters align with the design requirements.
