CMT-1603-SMT-TR

Alarms, Buzzers, And Sirens Overview

The CMT-1603-SMT-TR is a piezoelectric audio transducer buzzer manufactured by Same Sky. It operates at a rated voltage of 3 V with a peak-to-peak input signal type and draws 3 mA of supply current. The device produces a sound pressure level of 70 dB at 3 V measured at 10 cm distance, operating at a frequency of 4 kHz. Its physical dimensions are 16.00 mm in length and width, with a maximum installation height of 2.80 mm. The component supports surface mount technology (SMT) termination and functions within a temperature range of -30°C to 70°C.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the manufacturer designation as Same Sky, formerly CUI Devices, to ensure accurate sourcing. Confirm the SMT suffix indicates surface mount termination compatible with standard pick-and-place processes. Check RoHS compliance documentation for environmental regulatory adherence. Validate the specific tape and reel packaging configuration against production line requirements.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, surface-mountable piezoelectric buzzer is required for compact designs. Ensure the driving circuit can provide the necessary 3 V peak-to-peak signal at 4 kHz. Consider the 70 dB SPL output sufficient for the intended acoustic environment. Verify that the 16x16 mm footprint fits within the available board space constraints.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CMT series of audio transducers from Same Sky. It serves as a direct replacement for legacy CUI Devices components in existing designs. The series offers various sizes and acoustic outputs to suit different enclosure volumes and alert intensity needs.

Alarms, Buzzers, And Sirens Replacement Considerations

Check pinout compatibility if substituting in existing footprints. Verify acoustic performance matches original design specifications.
