Speakers Procurement Notes

Verify the specific part number CMS-3049-058SP against official Same Sky documentation to confirm current manufacturing status and technical specifications. Ensure that the solder pad termination method aligns with the target printed circuit board layout. Cross-reference environmental compliance data such as RoHS status directly from the manufacturer's datasheet before finalizing procurement decisions.

Speakers Selection Notes

Select this component when a low-profile 30 mm round speaker is required. The 8 Ohm impedance matches standard amplifier outputs. The 0.5 W rating suits low-volume signaling or voice applications. Verify that the 620 Hz to 6 kHz frequency range meets the acoustic requirements of the specific end-use environment.

Speakers Part Context

This model belongs to the Same Sky miniature speaker series, designed for integration into compact electronic assemblies. The product line emphasizes small form factors without compromising acoustic performance. The use of rare earth magnets allows for reduced size while maintaining necessary magnetic flux density for efficient sound generation.
