CMS-301103-154SP

Speakers Overview

The CMS-301103-154SP is a rectangular miniature speaker manufactured by Same Sky. It features a 30 mm x 11 mm footprint with a 3 mm depth. The unit utilizes a Neodymium Iron Boron (NdFeB) magnet and a Polyether ether ketone (PEEK) cone. Rated impedance is 4 Ohms with a power handling capacity of 1.5 W. The resonant frequency is specified at 500 Hz, and it employs solder pad termination for board mounting.

Speakers Feature Summary

• Rectangular form factor designed for space-constrained applications
• High-performance PEEK cone material for durability
• Neodymium magnet assembly for efficient acoustic output

Speakers Applications

• Miniature audio devices
• Portable electronic equipment
• Medical instrumentation

Speakers Procurement Notes

Verify the specific impedance and power rating against the target circuit design to ensure compatibility. Confirm that the rectangular solder pad layout matches the printed circuit board footprint exactly. Check RoHS compliance documentation if required by the end product regulations. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Speakers Selection Notes

Select this component when a rectangular shape is required instead of standard circular speakers. The 4 Ohm impedance suits low-voltage battery-powered systems. The PEEK cone offers superior thermal stability compared to paper or PET cones. Consider the 1.5 W power rating for moderate volume applications in small enclosures.

Speakers Part Context

This model belongs to the Same Sky miniature speaker series, formerly associated with CUI Devices. It represents a specialized geometry within the broader audio transducer portfolio, catering to designs where standard round drivers do not fit the available chassis space.

Speakers Replacement Considerations

Direct replacements must match the 30x11x3 mm dimensions and 4 Ohm impedance. Verify that alternative rectangular speakers maintain similar magnetic strength and cone material properties to preserve acoustic performance.
