CMS-151125-078SP

Speakers Overview

The CMS-151125-078SP 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 device utilizes a neodymium magnet and includes solder pads for board mounting. Its resonant frequency is specified at 900 Hz, delivering a sound pressure level of 92 dBa. The unit functions within a temperature range of -20°C to +70°C.

Speakers Feature Summary

• Rectangular form factor designed for compact electronic assemblies
• Neodymium magnet construction for efficient audio output
• Solder pad termination for direct PCB integration

Speakers Applications

• Portable consumer electronics
• Medical devices requiring small audio components
• Industrial control panels

Speakers Procurement Notes

Verify the specific suffix SP against official Same Sky documentation to confirm solder pad termination type. Ensure environmental ratings align with operational requirements. Cross-reference manufacturer part numbers to avoid confusion with similar models in the CMS series. Confirm RoHS compliance status through current datasheets before procurement.

Speakers Selection Notes

Select this component when a rectangular footprint fits the design constraints better than circular alternatives. Consider the 8-ohm impedance for amplifier matching. Evaluate the 900 Hz resonant frequency against required audio bandwidth. Compare physical dimensions against available board space to ensure proper fitment during assembly.

Speakers Part Context

This model belongs to the Same Sky CMS micro speaker series, which offers various frame shapes and sizes. The CMS-151125 variant specifically provides a rectangular profile distinct from round speakers like the CMS-23558N. It shares the 15x11 mm dimension family with other rectangular options but differs in electrical characteristics and termination style.

Speakers Replacement Considerations

CMS-151135-078L100B-67 offers similar dimensions but uses wire leads instead of solder pads. CMS-15113-076SP features a 6-ohm impedance and different resonant frequency. Verify mechanical compatibility and electrical parameters before substituting.
