CMS-2847-048SP

Speakers Overview

The CMS-2847-048SP is a miniature round speaker manufactured by Same Sky. It features a 28 mm diameter frame with a depth of 4.7 mm. The unit utilizes a rare earth neodymium magnet and has an impedance of 8 ohms. Rated power is 0.4 W, with a self-resonant frequency of 540 Hz. The device employs solder pad termination for circuit board mounting.

Speakers Feature Summary

• Compact round frame design suitable for space-constrained applications
• Utilizes rare earth neodymium magnet technology
• Direct solder pad termination for PCB integration

Speakers Applications

• Miniature audio devices
• Portable consumer electronics
• Medical equipment speakers
• Industrial control panels

Speakers Procurement Notes

Verify the specific datasheet version to confirm mechanical tolerances and acoustic performance curves. Ensure soldering temperature profiles comply with thermal limits for the PEI cone material. Confirm that the 8-ohm impedance matches the amplifier output requirements for optimal power transfer.

Speakers Selection Notes

Select this component when a low-profile, round speaker is required. The 4.7 mm depth allows for thin enclosure designs. The 8-ohm impedance is standard for many audio driver circuits. Consider the 0.4 W power rating for low-volume signal indication or voice prompts rather than high-fidelity music reproduction.

Speakers Part Context

This part belongs to the Same Sky miniatures speaker family, formerly associated with CUI Devices. These components are designed for general-purpose audio output in small form-factor devices. The series offers various impedances and power ratings to suit different driver capabilities.

Speakers Replacement Considerations

Check mechanical dimensions against existing footprints. Verify electrical compatibility including impedance and resonant frequency. Ensure the replacement supports the same soldering process and environmental operating conditions.
