SMT-0927-S-11-R

Alarms, Buzzers, And Sirens Overview

The SMT-0927-S-11-R is a piezo-based surface mount transducer manufactured by PUI Audio. It operates with an externally driven circuit and supports a rated voltage of 3.6 V peak-to-peak, within an operating range of 2.5 to 4.5 V peak-to-peak. The device draws a maximum current of 90 mA at rated voltage and produces a sound pressure level of 90 dB measured at 10 cm distance. Its resonant frequency is specified at 2.67 kHz. The component utilizes a surface mount package with dimensions of 8.5 mm x 8.5 mm and a maximum height of 3 mm.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage and acoustic specifications. Confirm that the external driving circuitry can supply the required peak-to-peak voltage and current limits without exceeding the component's maximum ratings. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, low-profile audible signal is required for battery-operated or power-sensitive applications. Ensure the host PCB layout accommodates the 8.5 mm square footprint and 3 mm height constraint. Verify that the application environment falls within the standard operating temperature range for piezo ceramic materials.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SMT-09 series of piezo transducers from PUI Audio. The series is characterized by its small physical size and suitability for surface mount technology. It serves as a direct replacement for through-hole transducers in designs requiring reduced profile and automated manufacturing compatibility.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with SMT-0927-T-2-R for alternative magnetic buzzer options if different drive characteristics are needed. Verify mechanical mounting holes and electrical polarity requirements before substituting with other series components.
