Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and specific packaging options such as tape and reel quantities prior to ordering. Ensure that the selected variant matches the required voltage rating and mounting specifications for the target application environment.
Selection Notes
Select this component when a surface-mount solution with integrated driving capability is required. The 12 VDC rating suits standard logic-level power supplies. Consider the 85 dB SPL for environments needing clear auditory indication. Verify spatial constraints against the 9.60 mm x 9.60 mm footprint and 5.30 mm height limits.
Part Context
This part belongs to the CMI series of magnetic buzzers manufactured by Same Sky. The series offers various voltage options and form factors for audio alert applications. The SMT designation indicates surface-mount technology compatibility, facilitating automated assembly processes on printed circuit boards.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the same product family. Verify pinout compatibility and mechanical dimensions before replacing existing components in established designs.
