CMS-15118D-SP

Speakers Overview

The CMS-15118D-SP is a low-profile rectangular speaker manufactured by Same Sky. It features an 8-ohm impedance and a power rating of 700 mW. The unit measures 15 x 11 mm with a depth of 3 mm, utilizing a neodymium magnet for efficient performance. Designed for board mount applications via solder pads, it offers a frequency response range from approximately 425 Hz to 10 kHz. This component is suitable for compact electronic designs requiring reliable audio output within strict spatial constraints.

Speakers Feature Summary

• Low-profile rectangular design optimized for space-constrained PCB layouts
• Neodymium magnet construction ensures high efficiency in a small form factor
• Solder pad termination facilitates direct surface-mount assembly

Speakers Applications

• Portable consumer electronics
• Medical diagnostic devices
• Industrial control panels

Speakers Procurement Notes

Verify the specific suffix and manufacturer designation when sourcing, as product lines may transition between CUI Devices and Same Sky. Confirm that the 8-ohm impedance and 700 mW rating align with the target circuit requirements. Ensure the rectangular footprint matches the designated board area. Cross-reference the latest datasheet for any updates regarding material composition or environmental compliance standards before finalizing procurement.

Speakers Selection Notes

Select this model when a compact, rectangular acoustic solution is required for low-power audio signaling. The 8-ohm impedance is compatible with many standard amplifier outputs. Consider the 3 mm depth limit to ensure mechanical clearance. Evaluate the 425 Hz lower frequency limit against application needs, as it may not support deep bass reproduction. Verify solder pad compatibility with the chosen assembly process.

Speakers Part Context

This component belongs to the Same Sky (formerly CUI Devices) line of miniature speakers. It is part of a series designed for integration into portable and industrial devices where size is a critical constraint. The rectangular shape distinguishes it from circular counterparts, allowing for more efficient use of rectangular PCB real estate. It represents a balance between acoustic performance and physical miniaturization.

Speakers Replacement Considerations

Check for CMS-15113-076SP or CMS-151135-078L100B-67 if different impedance or mounting styles are acceptable. Verify dimensional compatibility before substitution. Ensure electrical parameters match the original design intent.
