SMT-1427-S-4-R is listed in the Alarms, Buzzers, And Sirens range at ChipApex. The manufacturer field lists PUI Audio, Inc.. Its product description is BUZZER MAGNETIC 5V 11X14MM SMD. Review the specifications below when checking this part for your BOM.
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.
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.
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.
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.
No public substitute part numbers are documented for this specific model.
