CMT-0502-75-SMT-TR

Alarms, Buzzers, And Sirens Overview

The CMT-0502-75-SMT-TR is a magnetic audio transducer buzzer manufactured by Same Sky. It features a surface-mount design with dimensions of 5 mm x 5 mm x 3 mm. The component operates at a nominal voltage of 3 V and has a resonant frequency of 4 kHz. It produces a sound pressure level of 75 dB when measured at a distance of 10 cm with a 3 V input. The device draws a current of 100 mA and utilizes external drive circuitry for operation.

Alarms, Buzzers, And Sirens Feature Summary

• Surface-mount construction suitable for automated PCB assembly
• Magnetic transducer technology for external signal driving
• Compact 5 mm square footprint with low profile height

Alarms, Buzzers, And Sirens Applications

• Electronic device status indicators
• Audible alert systems in consumer electronics
• Embedded sound signaling in compact hardware

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific package variant, as suffixes may indicate different reel or tape configurations. Confirm RoHS compliance status through official documentation before integration. Ensure drive circuits match the 3 V nominal requirement to maintain specified acoustic performance and prevent damage.

Alarms, Buzzers, And Sirens Selection Notes

Select this component for applications requiring a low-profile, externally driven magnetic buzzer. Compare against piezoelectric alternatives if higher efficiency or integrated oscillator functionality is required. Verify that the 100 mA current draw aligns with the target system's power budget and driver capabilities.

Alarms, Buzzers, And Sirens Part Context

This part belongs to Same Sky's line of surface-mount audio transducers. It is designed for integration into portable devices where space constraints limit the use of through-hole components. The magnetic type requires an external AC signal source to generate sound, distinguishing it from self-oscillating piezo buzzers.
