Overview
The CMI-9705-85-SMT-TR is an electromagnetic audio transducer manufactured by Same Sky, designed for surface-mount technology (SMT) applications. It operates within a DC voltage range of 8 to 15 volts and produces a sound pressure level of 85 dB at a frequency of 3 kHz. The component features a compact form factor suitable for space-constrained PCB designs, utilizing SMD/SMT termination types for automated assembly processes.
Feature Summary
- Electromagnetic transduction mechanism for audible signaling
- Surface-mount design compatible with automated PCB assembly
- Wide operating voltage range supporting various logic levels
Applications
- Electronic equipment status indicators
- Consumer appliance alert systems
- Industrial control panel signaling
Procurement Notes
Verify the specific voltage tolerance and current consumption requirements against your circuit design before procurement. Confirm that the surface-mount footprint matches your PCB layout exactly. Ensure the supply chain source provides authentic Same Sky components to guarantee acoustic performance consistency and long-term reliability in your final product assembly.
Selection Notes
Select this component when a high-decibel audible alert is required in a low-profile surface-mount package. The wide voltage input range offers flexibility in power supply design compared to fixed-voltage alternatives. Consider the electromagnetic drive type if higher sound pressure is needed relative to piezoelectric options of similar size.
Part Context
This part belongs to the Same Sky CMI series of electromagnetic buzzers. These devices are engineered for reliable audio indication in commercial and industrial electronics. The series emphasizes compact dimensions and robust acoustic output, catering to modern electronic designs requiring efficient space utilization and clear auditory feedback mechanisms.
Replacement Considerations
Direct substitutes may include other 85 dB, 3 kHz surface-mount electromagnetic buzzers from the same manufacturer. Verify pinout compatibility and mechanical dimensions before swapping. Alternative technologies like piezoelectric variants offer different drive characteristics but may not match the exact acoustic profile.
