CMS-181325-078SP

Speakers Overview

The CMS-181325-078SP is a rectangular general-purpose speaker manufactured by Same Sky. It features an 8 Ohm impedance and a 700 mW power rating, with a maximum power handling of 1 W. The unit utilizes a Neodymium Iron Boron (NdFeB) magnet and a Polyethylene Terephthalate (PET) cone. It delivers a sound pressure level of 93 dBA at 700 mW/100mm. The frequency range spans from 500 Hz to 10 kHz, with a self-resonant frequency of 800 Hz. Dimensions are 18.00 mm x 13.00 mm x 2.50 mm, and it uses solder pad termination.

Speakers Feature Summary

• Rectangular form factor with top port configuration for acoustic output
• Utilizes NdFeB magnetic material and PET cone construction
• Designed for board mount installation via solder pads

Speakers Applications

• General purpose audio transduction in compact electronic devices
• Integration into miniature enclosures requiring top-port acoustic design
• Applications utilizing standard 8 Ohm impedance audio circuits

Speakers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required termination types and acoustic specifications. Confirm that the 700 mW rated power aligns with the target application's drive requirements. Check for any recent revisions to the CMS-181325 series documentation regarding material compliance or dimensional tolerances prior to finalizing procurement orders.

Speakers Selection Notes

Select this component when a low-profile rectangular speaker with top-port acoustics is required. The 8 Ohm impedance suits standard audio driver outputs. Ensure the enclosure design accommodates the 18.00 mm x 13.00 mm footprint and 2.50 mm height. Consider the 500 Hz lower frequency limit for applications requiring bass response, as this model is optimized for mid-range frequencies.

Speakers Part Context

This part belongs to the Same Sky CMS series of micro speakers. The series offers various impedance and power options within standardized rectangular footprints. The CMS-181325 variant specifically targets space-constrained designs needing reliable performance from a small form factor. It represents a standard solution for consumer electronics and industrial control panels requiring audible feedback.

Speakers Replacement Considerations

Check the CMS-181325-076SP for a 6 Ohm alternative. Verify CMS-181325-084SP for different impedance configurations. Consult the official Same Sky cross-reference guide for exact mechanical and electrical equivalents.
