• Surface mount construction optimized for automated PCB assembly processes
• Magnetic transducer mechanism providing consistent performance across operating conditions

Alarms, Buzzers, And Sirens Applications

• Consumer electronics audio alerts
• Industrial equipment status indicators
• Medical device alarm systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 3.6 V rating matches the target circuit supply voltage to prevent damage or insufficient actuation. Cross-reference the 90 dB sensitivity specification against application noise floor requirements.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact 8.5 mm square footprint is required for high-volume surface mount production. Choose this model over through-hole alternatives to save board space and reduce assembly costs. Consider the 3.1 kHz resonant frequency for optimal audibility in standard environments. Verify that the 90 mA current draw is supported by the driving circuit's output capability.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky CMT series of magnetic buzzers, formerly associated with CUI Devices. The series offers various sizes and sound pressure levels. The CMT-8503 variant specifically denotes the 8.5 mm form factor within the product line, distinguishing it from smaller or larger counterparts in the same family.

Alarms, Buzzers, And Sirens Replacement Considerations

The CMT-8503-87-SMT-TR and CMT-8503-97-SMT-TR are confirmed substitutes within the same physical package and electrical family. These alternatives offer different sound pressure levels (87 dB and 97 dB respectively) while maintaining identical mounting dimensions and voltage ratings.
