Alarms, Buzzers, And Sirens Procurement Notes

Verify the manufacturer part number against official Same Sky documentation to confirm specifications. Ensure the ordering suffix matches the required packaging format, such as tape and reel or cut tape. Confirm RoHS compliance status through the product datasheet. Validate that the drive circuitry supports the 3.6 V nominal voltage and 100 mA current requirements before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact magnetic buzzer with high acoustic output is required. The 85 dB sensitivity provides clear audibility in moderate noise environments. Verify that the PCB layout accommodates the 7.5 mm square footprint and 3.1 mm height clearance. Ensure the driving circuit can handle the 100 mA current draw without exceeding power supply limits.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the CMT series of magnetic audio transducers from Same Sky. The series offers various voltage and sensitivity options within a standardized surface mount package. The CMT-7525-85 variant specifically targets applications requiring higher sound pressure levels compared to lower sensitivity models in the same physical envelope.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 7.5 mm x 7.5 mm footprint, 3.6 V nominal voltage, and magnetic transducer type. Verify equivalent sound pressure level and current consumption to ensure functional compatibility. Check for identical mounting orientation and terminal configuration.
