CMS-151125-078S-67

Speakers Overview

The CMS-151125-078S-67 is a micro speaker manufactured by Same Sky, designed for board mount applications. It features a rectangular shape with dimensions of 15 mm in length and 11 mm in width. The unit operates at an impedance of 8 ohms and has a power rating of 700 mW. Key electrical parameters include a resonant frequency of 850 Hz and a sound pressure level of 91 dBa. The device utilizes wire leads for termination and incorporates a neodymium magnet with a PEEK cone. It is rated for operation between -20°C and +70°C.

Speakers Feature Summary

• Utilizes a neodymium magnet and PEEK cone for acoustic performance
• IPX7 water resistance rating for environmental protection
• Rectangular form factor suitable for compact board mounting

Speakers Applications

• Consumer electronics audio output
• Industrial control panel signaling
• Medical device acoustic alerts

Speakers Procurement Notes

Verify the specific suffix '67' against official datasheets to confirm connector type and lead configuration. Ensure the 8-ohm impedance matches the amplifier output requirements. Confirm IPX7 rating necessity for the target environment. Cross-reference the 700 mW power handling with thermal management capabilities in the final assembly.

Speakers Selection Notes

Select this component when a rectangular micro speaker with IPX7 protection is required. Compare the 850 Hz resonant frequency against application needs for low-frequency response. Evaluate the 15x11 mm footprint against available PCB space. Consider the wire lead termination method versus solder pad alternatives if automated assembly is prioritized.

Speakers Part Context

This part belongs to the Same Sky CMS series of micro speakers. It shares dimensional similarities with other models in the 15x11 mm family but differs in impedance, power rating, and termination style. The series offers various configurations including different magnet types and cone materials to suit diverse acoustic and mechanical constraints.

Speakers Replacement Considerations

CMS-151135-078L100B-67: Similar rectangular form factor and 8-ohm impedance, but verify lead configuration differences.
