Alarms, Buzzers, And Sirens Procurement Notes

Verify the manufacturer designation as Same Sky (Formerly CUI Devices) against official component documentation. Confirm that the ordering suffix TR indicates tape and reel packaging suitable for surface mount processing. Ensure the specific model number matches the required acoustic parameters before procurement. Cross-reference datasheet specifications for thermal and electrical limits.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-decibel magnetic buzzer is required for surface mount manufacturing processes. The 3.6 Vp-p rating suits low-voltage logic-driven circuits. Consider the 8.5 mm footprint and side-port orientation for mechanical integration. Evaluate the 100 mA current draw against available driver capacity in the target application circuit.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CMT series of magnetic audio transducers from Same Sky. The series provides various sound pressure levels and drive voltages for different alert requirements. The CMT-8504-99 variant specifically targets applications needing high volume output within a compact surface mount package. It complements piezoelectric alternatives where higher efficiency at lower frequencies is preferred.
