Alarms, Buzzers, And Sirens Procurement Notes
Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the operating voltage requirements align with the system power supply rails. Ensure the PCB footprint matches the specified SMD pad layout to guarantee proper mechanical and electrical connection during assembly.
Alarms, Buzzers, And Sirens Selection Notes
Select this component when a low-profile, high-output buzzer is required for surface-mount assembly. The 87 dB output provides clear audible indication in moderate noise environments. Consider the 90 mA current draw when designing the power distribution network to ensure stable operation without excessive voltage drop.
Alarms, Buzzers, And Sirens Part Context
This part belongs to the Same Sky CMT series of electromagnetic buzzers. These components are designed as direct replacements for legacy through-hole or larger surface-mount buzzers where space is limited. The series offers various SPL and voltage options within a standardized footprint family.
Alarms, Buzzers, And Sirens Replacement Considerations
Direct substitutes include the CMT-8504-03-SMT-TR and CMT-8503-87-SMT-TR from the same manufacturer, provided their voltage and acoustic specifications meet the application requirements.
