CMS-15118E-SP

Speakers Overview

The CMS-15118E-SP is a rectangular micro speaker manufactured by Same Sky. It features an 8-ohm impedance and an 800 mW power rating. The unit measures 15 mm in length and 11 mm in width, with a height of 2.5 mm. It utilizes a neodymium iron boron magnet and a polyetheretherketone cone. The sound pressure level is rated at 90.5 dBA. Termination is provided via spring contacts for board mounting.

Speakers Feature Summary

• Utilizes a neodymium iron boron magnet for efficient acoustic output
• Constructed with a polyetheretherketone cone material
• Features a low-profile rectangular frame design

Speakers Applications

• Portable electronic devices requiring compact audio output
• Consumer electronics with limited internal space
• Industrial control panels needing audible indicators

Speakers Procurement Notes

Verify the specific termination style required for your PCB layout, as this model uses spring contacts rather than traditional solder pads. Confirm that the mechanical dimensions align with your enclosure constraints. Ensure the driving circuit can handle the specified impedance and power levels to prevent damage. Check for RoHS compliance documentation if required by your regional regulations.

Speakers Selection Notes

Select this component when a low-profile rectangular form factor is necessary. The 8-ohm impedance suits standard audio driver circuits. Consider the 90.5 dBA sensitivity for applications requiring moderate volume without excessive power consumption. The spring contact termination may influence assembly methods compared to solder pad alternatives.

Speakers Part Context

This part belongs to the Same Sky micro speaker lineup, formerly associated with CUI Devices. It is designed for board-mount applications where space is constrained. The series offers various impedance and power options to suit different audio requirements in portable and industrial equipment.

Speakers Replacement Considerations

Direct substitutes must match the 15x11mm outline, 8-ohm impedance, and spring contact termination. Verify that alternative speakers maintain similar sound pressure levels and power handling capabilities to ensure consistent performance in the final application.
