CLS0281MAE-L152

Overview

The CLS0281MAE-L152 is a small-size electromagnetic speaker manufactured by Same Sky. It features an 8-ohm impedance and a rated power of 500 mW, with a maximum power handling capacity of 1 W. The unit utilizes a Neodymium Iron Boron (Nd-Fe-B) magnet and a Polyethylene Terephthalate (PET) cone. Designed for top porting, it delivers an efficiency of 88 dBA at 1W/500mm. The frequency range spans from 540 Hz to 6 kHz, with a self-resonant frequency of 660 Hz. Physical dimensions include a 26.00 mm diameter and a maximum installation height of 4.50 mm.

Feature Summary

• Top-port design facilitates direct sound projection without rear enclosure requirements.
• Compact circular form factor enables integration into space-constrained electronic devices.
• Wire lead termination allows for flexible connection to driver circuits.

Applications

• Portable consumer electronics requiring compact audio output
• Medical equipment needing reliable acoustic signaling
• Industrial control panels for status indication

Procurement Notes

Verify the specific suffix L152 to confirm wire lead configuration and port orientation. Ensure the receiving environment accommodates the 4.50 mm maximum height constraint. Confirm RoHS3 compliance requirements align with project specifications before finalizing procurement orders.

Selection Notes

Select this component when a top-firing acoustic profile is required within a 26 mm diameter footprint. The 8-ohm impedance matches standard low-voltage audio drivers. Consider the 500 mW rating against continuous drive levels to prevent thermal damage during operation.

Part Context

This model belongs to the CLS series of miniature speakers from Same Sky. The series emphasizes high efficiency in small packages using magnetic materials like Nd-Fe-B. It serves as a specialized audio transducer option distinct from larger frame or PCB-mount variants.

Replacement Considerations

CLS0261MAE-L152 offers similar top-port functionality but with a smaller 26 mm diameter and lower power rating. Verify dimensional compatibility and acoustic performance differences before substitution.
