CMS-151125-078L100B

Overview

The CMS-151125-078L100B is a miniature rectangular speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 0.7 W, with a maximum power handling capacity of 1 W. The device utilizes a neodymium magnet and a polyester (PET) diaphragm. Its frequency response ranges from 700 Hz to 20 kHz, with a self-resonant frequency of approximately 910 Hz. The unit measures 15 mm x 11 mm x 2.5 mm and employs wire leads for termination.

Feature Summary

• Compact rectangular form factor suitable for space-constrained designs
• High sound pressure level efficiency for clear audio output
• Robust construction using neodymium magnets and PET diaphragms

Applications

• Portable consumer electronics
• Medical devices requiring compact audio solutions
• Industrial control panels

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required impedance and power ratings. Confirm that wire lead termination meets the assembly requirements. Cross-reference the manufacturer part number with current distributor listings to validate availability and authenticity before finalizing procurement orders.

Selection Notes

Select this component when a small footprint is critical alongside moderate acoustic performance. The 8 Ohm impedance suits standard driver circuits. Ensure the operating environment does not exceed the thermal limits defined in the datasheet. Compare against IP-rated variants if environmental sealing is required for the target application.

Part Context

This model belongs to the CMS series of micro speakers from Same Sky, formerly CUI Devices. The series offers various sizes and mounting options. This specific variant focuses on delivering efficient audio output within a minimal rectangular envelope, leveraging neodymium magnetic technology for enhanced performance relative to its physical dimensions.

Replacement Considerations

Check for CMS-151125-078L100B-67 if IP67 waterproofing is needed instead of the standard version. Verify dimensional compatibility with existing enclosures when substituting.
