CMS-160916A-SP

Overview

The CMS-160916A-SP is a miniature rectangular speaker manufactured by Same Sky. It features a 16 x 9 mm frame with a power rating of 0.8 W and an impedance of 6 Ohms. The self-resonant frequency is specified at 650 Hz, providing efficient audio output for compact designs. This component utilizes neodymium magnet technology to ensure high performance within its small physical footprint.

Feature Summary

• Rectangular micro-speaker design optimized for space-constrained applications
• Utilizes neodymium magnet technology for enhanced acoustic efficiency
• Solder pad termination style facilitates direct board mounting

Applications

• Portable consumer electronics requiring compact audio solutions
• Medical devices with limited internal volume
• Industrial control panels needing audible feedback

Procurement Notes

Verify the specific suffix 'A' against official Same Sky documentation to confirm exact electrical tolerances and material specifications. Ensure soldering parameters align with the manufacturer's thermal guidelines to prevent damage during assembly. Cross-reference the part number with current datasheets to confirm availability and any recent design changes.

Selection Notes

Select this component when a rectangular form factor is required for tight spatial constraints. The 6 Ohm impedance and 0.8 W rating suit low-power driver circuits. Consider the 650 Hz resonance point for voice or alert tones rather than full-range music reproduction. Verify enclosure compatibility with the 16 x 9 mm dimensions.

Part Context

This model belongs to the Same Sky CMS series of miniature speakers, formerly associated with CUI Devices. The series offers various sizes and shapes, including round and oval options. The CMS-160916A-SP specifically addresses needs for rectangular footprints in portable and embedded systems where standard circular speakers do not fit.

Replacement Considerations

Direct substitutes may include other 16x9mm rectangular speakers from Same Sky or competitors with matching 6 Ohm impedance and similar power ratings. Verify mechanical dimensions and terminal type before substitution.
