CMT-13031-SMT-TR

Alarms, Buzzers, And Sirens Overview

The CMT-13031-SMT-TR is a surface-mount piezoelectric buzzer transducer manufactured by Same Sky. It operates with an external driver circuit and accepts a peak-to-peak voltage input of up to 25 V. The device produces a sound pressure level of 70 dB at a resonant frequency of 4.1 kHz. Its compact footprint measures 13 mm by 13 mm with a maximum height of 3.1 mm, designed for direct soldering onto printed circuit boards.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric transduction mechanism requiring external drive signals
• Surface mount termination for automated PCB assembly
• Compact low-profile housing suitable for space-constrained designs

Alarms, Buzzers, And Sirens Applications

• Electronic equipment status indicators
• Appliance audio alerts
• Industrial control panel signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the driving circuitry can supply the required peak-to-peak voltage without exceeding component limits. Ensure the PCB footprint matches the recommended land pattern to guarantee reliable solder joint integrity during reflow processes.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-output audible alert is required in a small form factor. The piezoelectric type offers lower current consumption compared to electromagnetic alternatives. Verify that the application environment remains within the specified operating temperature range to maintain consistent acoustic performance and mechanical stability.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CMT series of audio transducers from Same Sky. The series provides various sizes and acoustic outputs for different enclosure requirements. The SMT suffix indicates surface mount technology compatibility, distinguishing it from through-hole variants in the same product family.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other 13mm x 13mm piezo buzzers with similar 70 dB SPL ratings. Check pinout compatibility and mounting hole positions to ensure mechanical interchangeability without redesigning the PCB layout.
