Overview
The CMI-1265-88-SMT-TR is a surface-mount magnetic audio transducer manufactured by Same Sky. It features an internal driving circuit and operates within a voltage range of 4V to 7V DC, with a typical nominal voltage of 5V. The device produces a sound pressure level of 88 dB at 10 cm distance. Its physical dimensions are 12.8 mm x 12.8 mm x 7.1 mm, utilizing a Polyphenylene Sulphide (PPS) body. The component is designed for PCB mounting via SMD/SMT termination.
Feature Summary
- Integrated internal driving circuit simplifies interface requirements
- Magnetic transduction mechanism ensures reliable acoustic output
- Polyphenylene Sulphide (PPS) housing provides structural stability
Applications
- Electronic equipment status indication
- Alarm systems requiring audible alerts
- Consumer appliance user feedback interfaces
Procurement Notes
Verify the specific operating voltage and current consumption against the official datasheet before integration. Confirm that the 12.8 mm footprint matches the target PCB layout. Ensure the supply chain source provides genuine Same Sky components to guarantee acoustic performance consistency and long-term reliability in final assemblies.
Selection Notes
Select this component when a compact, self-driving buzzer is required for space-constrained designs. The 88 dB output suits applications needing clear audible notification without external amplification. Consider the 7.1 mm height profile for enclosure clearance constraints. Verify compatibility with standard reflow soldering profiles for SMT assembly processes.
Part Context
This part belongs to the Same Sky family of surface-mount audio indicators. It replaces legacy through-hole or externally driven buzzers by integrating control electronics directly into the package. The model designation indicates its magnetic type, acoustic output level, and surface-mount configuration within the manufacturer's product portfolio.
Replacement Considerations
Direct substitutes include other 12.8 mm surface-mount magnetic buzzers with integrated drivers. Verify pinout compatibility and acoustic center alignment when swapping manufacturers. Check if alternative parts meet the same 88 dB sensitivity requirement at the specified operating voltage range.
