Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required voltage and frequency parameters. Confirm that the gullwing lead package matches the target PCB footprint design. Check RoHS compliance documentation for regulatory adherence in the destination market. Ensure handling procedures account for humidity sensitivity during storage and reflow soldering processes.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact square form factor is required for space-constrained designs. The 10x10 mm footprint supports standard surface-mount assembly lines. Consider the 93 dBA output level for audible notification requirements without excessive power consumption. The 3.6 V rating aligns with common low-voltage logic systems.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SMT-10 series of surface-mount transducers from PUI Audio. The series offers various configurations differing in voltage, frequency, and acoustic output. The SMT-1028 variant specifically targets high-frequency single-tone applications requiring minimal profile integration into printed circuit boards.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include the SMT-1028-T-2-R, which shares identical physical dimensions and electrical characteristics but may differ in specific acoustic tuning or packaging variations. Verify pinout and mechanical tolerances before substitution.
