CMS-18138-25-SP

Speakers Overview

The CMS-18138-25-SP is an 18 mm diameter, 13 mm deep speaker transducer manufactured by Same Sky. It features a paper cone and NdFeB magnet with a nominal impedance of 8 ohms and a power rating of 0.7 W. The unit operates at a resonant frequency of 480 Hz and delivers a sound pressure level of 90.5 dB. Electrical connections are provided via top-mounted spring terminals for secure attachment.

Speakers Feature Summary

• Utilizes a paper cone and neodymium iron boron (NdFeB) magnet assembly for acoustic performance
• Equipped with top-mounted spring terminals for direct wire connection without soldering
• Designed for compact integration within constrained electronic enclosures

Speakers Applications

• Consumer electronics audio output modules
• Industrial control panel signaling devices
• Compact appliance status indicators

Speakers Procurement Notes

Verify the current lifecycle status as the component is listed as obsolete in distributor records. Confirm availability of alternative sources or final time buys if immediate procurement is required. Ensure compatibility with existing spring-terminal mounting structures during replacement planning.

Speakers Selection Notes

Select this model when a low-profile 18 mm speaker with spring terminals is required. The 8-ohm impedance and 0.7 W rating suit low-power applications. Verify that the 480 Hz resonance aligns with the target frequency response requirements for the specific audio application.

Speakers Part Context

This component belongs to the Same Sky speaker and transducer product line. It represents a standard size category for small-format audio output devices. The manufacturer provides datasheets detailing mechanical dimensions and electrical characteristics for design integration.

Speakers Replacement Considerations

Check for active equivalents from Same Sky or other manufacturers offering identical 18 mm form factors and spring terminal interfaces. Ensure substitute parts match the 8-ohm impedance and 0.7 W power handling capabilities.
