CMS-15118-25-SP

Speakers Overview

The CMS-15118-25-SP is a rectangular general-purpose speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated input power of 0.7 W, with a maximum capacity of 1 W. The unit delivers a sound pressure level of 91.5 dBA and operates within a frequency range of 400 Hz to 20,000 Hz. Constructed with a PET cone and Nd-Fe-B magnet, it utilizes pad termination for surface mounting. Physical dimensions are 18.00 mm in length, 13.00 mm in width, and 2.50 mm in height.

Speakers Feature Summary

• Rectangular form factor designed for compact audio applications
• Utilizes Neodymium Iron Boron magnetic structure for efficient performance
• Polyester diaphragm construction for durability

Speakers Applications

• Consumer electronic devices requiring small form factor audio output
• Portable gadgets with limited internal space constraints
• General purpose signaling or alert systems

Speakers Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to ensure correct acoustic and electrical characteristics. Confirm RoHS compliance status through current certification records. Cross-reference the DigiKey part number 102-4630-ND for accurate sourcing and availability checks. Ensure compatibility with existing PCB layout requirements regarding pad termination style.

Speakers Selection Notes

Select this component when a low-profile rectangular speaker is required for tight spatial envelopes. The 8 Ohm impedance suits standard driver circuits without complex matching networks. Consider the 91.5 dBA sensitivity for volume requirements in enclosed spaces. Verify that the 400 Hz to 20 kHz frequency response meets the target application's audio fidelity needs.

Speakers Part Context

This model belongs to the CMS series of micro speakers from Same Sky. The series focuses on providing reliable audio solutions for medical and consumer electronics. The CMS-15118-25-SP represents a specific variant optimized for top-porting and surface mount integration within constrained device architectures.

Speakers Replacement Considerations

Consult official substitution guides for equivalent rectangular speakers with matching 8 Ohm impedance and similar physical dimensions. Verify that alternative components support pad termination and fit within the 18.00 mm x 13.00 mm footprint constraint.
