SMT-1427-S-4-R

Alarms, Buzzers, And Sirens Overview

The SMT-1427-S-4-R is an electromagnetic transducer manufactured by PUI Audio, designed for surface-mount board installation. It operates at a rated voltage of 5 V and draws a current of 90 mA. The device features a rectangular shape with gullwing lead termination, measuring 14 mm in length, 11 mm in width, and 3.3 mm in depth. It exhibits a self-resonant frequency of 2.7 kHz and delivers a sound pressure level of 87 dBA.

Alarms, Buzzers, And Sirens Feature Summary

Electromagnetic transduction mechanism optimized for surface-mount technology integration
Rectangular form factor with gullwing leads for direct PCB attachment
High acoustic output efficiency relative to compact physical dimensions

Alarms, Buzzers, And Sirens Applications

Electronic devices requiring compact audible alerting signals
Industrial control panels needing status indication tones
Consumer electronics utilizing limited board space for audio feedback

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'R' corresponds to the required reel packaging configuration during ordering. Confirm that the 5 VDC rating aligns with the target circuit's power supply rails. Ensure the gullwing lead footprint matches the design file exactly to prevent soldering defects. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-efficiency, low-profile electromagnetic solution is needed for rigid PCB mounting. The 2.7 kHz resonance provides distinct audibility for alarm applications. Consider the 90 mA current draw against available power budget constraints. The rectangular geometry allows for dense placement compared to circular alternatives.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SMT-14 series of surface-mount transducers from PUI Audio. The series focuses on providing robust audio signaling components that fit within strict height restrictions. It serves as a specialized alternative to through-hole buzzers where automated assembly and space conservation are critical design drivers.
