CMS-3648-038SP

Speakers Overview

The CMS-3648-038SP is a miniature round speaker manufactured by Same Sky. It features a 36 mm diameter frame with a depth of 4.8 mm. The unit utilizes a PEI cone material and a Neodymium (Nd-Fe-B) magnet for efficient audio output. Electrical specifications include an impedance of 8 ohms and a power rating of 0.3 W. The self-resonant frequency is specified at 430 Hz, with a sound pressure level of 101 dB. Termination is provided via solder pads.

Speakers Feature Summary

• Compact circular design suitable for space-constrained applications
• High-efficiency neodymium magnet construction
• Durable PEI cone material for consistent performance

Speakers Applications

• Miniature electronic devices requiring small form factor speakers
• Portable consumer electronics with limited internal volume
• Industrial control panels needing compact audio indicators

Speakers Procurement Notes

Verify the specific termination style matches your PCB layout requirements. Confirm that the 0.3 W power rating aligns with your system's drive capabilities to prevent damage. Ensure the 8-ohm impedance is compatible with your amplifier or driver circuitry. Check environmental operating conditions against the component specifications.

Speakers Selection Notes

Select this model when a low-profile, high-output speaker is required within a 36 mm footprint. Consider the 4.8 mm depth constraint during mechanical design. Evaluate the 101 dB sensitivity for adequate volume in the intended enclosure. Compare against other models in the series if different mounting styles or power ratings are needed.

Speakers Part Context

This component belongs to Same Sky's miniature speaker series, designed for integration into compact electronic assemblies. The brand, formerly known as CUI Devices, specializes in audio and interconnect solutions. This specific part represents a balance between size, acoustic performance, and manufacturing cost for standard consumer applications.

Speakers Replacement Considerations

The CMS-3648-18L200 serves as a comparable alternative within the same product family. Both share similar dimensions and magnetic materials but differ in power handling and termination methods. Verify electrical compatibility before substitution.
