Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'S-2-R' against official PUI Audio documentation to confirm the exact electrical characteristics, particularly the 92 dBA SPL and 15-ohm impedance values. Ensure the ordering information matches the required voltage range and package type before finalizing procurement to avoid functional mismatches in the design.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, square-form-factor transducer is required for space-constrained designs. The 2.7 kHz frequency provides a distinct audible tone suitable for alarms. Verify that the target application supports the 90 mA current draw and that the PCB layout accommodates the gullwing lead footprint dimensions.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the PUI Audio SMT series of surface-mount transducers. These components are engineered for high-volume manufacturing through standard pick-and-place equipment. The series offers various frequencies and sound pressure levels to meet diverse acoustic requirements in portable and embedded devices.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official PUI Audio substitution guides for verified equivalents. Cross-referencing with other SMT series parts requires matching the resonant frequency, impedance, and physical dimensions to ensure compatibility with existing acoustic enclosures and drive circuits.
