CMI-1210-90-SMT-TR

Overview

The CMI-1210-90-SMT-TR is a surface-mount magnetic audio indicator buzzer manufactured by Same Sky. It features an internally driven circuit for simplified integration. The device operates at a rated voltage of 5 VDC with a resonant frequency of approximately 2.5 kHz to 2.6 kHz. It delivers a sound pressure level of 90 dB and measures 12.8 mm x 12.8 mm x 10 mm.

Feature Summary

• Internally driven magnetic transducer design
• Surface mount (SMD) PCB installation
• High acoustic output capability

Applications

• Electronic equipment status indication
• Alarm systems
• Consumer appliance alerts

Procurement Notes

Verify the specific datasheet version for exact electrical tolerances and thermal soldering profiles. Confirm RoHS compliance status and packaging details such as reel quantity before finalizing orders. Ensure the driving circuit matches the internal driver requirements specified in the official documentation.

Selection Notes

Select this component when a compact, high-volume surface-mount solution is required. The integrated driver simplifies schematic design compared to passive buzzers. Verify that the 5V operating voltage aligns with the target system power rails and that the 90 dB output meets environmental noise requirements.

Part Context

This part belongs to the Same Sky CMI series of active magnetic buzzers. These components are designed for board-level audio signaling. The SMT variant facilitates automated assembly processes. Same Sky acquired CUI Devices, retaining these product lines under the new branding.

Replacement Considerations

Check for direct pin-compatible substitutes within the Same Sky CMI series. Verify that alternative parts match the 5V rating, 90 dB SPL, and 12.8mm footprint dimensions. Ensure the replacement also includes an internal driver circuit.
