CMS-151125-078L100

Overview

The CMS-151125-078L100 is a micro speaker manufactured by Same Sky, featuring a rectangular frame with dimensions of 15 mm in length and 11 mm in width. It operates at an impedance of 8 ohms and has a power rating of 700 mW. The unit utilizes a neodymium magnet and a PEEK cone for acoustic performance. Electrical characteristics include a resonant frequency of 850 Hz and a sound pressure level of 91 dB. The device is designed for board mount installation and includes wire leads for connection.

Feature Summary

• Rectangular form factor with integrated wire leads
• Neodymium magnet construction for efficient magnetic flux
• PEEK cone material for durability and acoustic clarity

Applications

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

Procurement Notes

Verify the specific suffix (e.g., A or B) against the required datasheet revision to ensure compatibility with connector types and lead configurations. Confirm that the 8-ohm impedance matches the amplifier output specifications of the target application circuit to prevent mismatch issues.

Selection Notes

Select this component when a small rectangular footprint is critical for the design. Ensure the operating temperature range of -20°C to +70°C meets the environmental requirements of the final assembly. Compare the 91 dB SPL against the necessary volume levels for the intended use case.

Part Context

This model belongs to the Same Sky CMS series of micro speakers. It shares the standard 15x11 mm rectangular housing geometry common across the family. Variations within the series typically differ in electrical parameters or terminal styles rather than physical dimensions.

Replacement Considerations

CMS-151125-078L100A and CMS-151125-078L100B are documented variants within the same product line. Verify if these alternatives offer identical mechanical mounting and electrical characteristics before substitution.
