CLS0281-L152

Overview

The CLS0281-L152 is a miniature round 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 device utilizes a neodymium iron boron magnet and a polyester cone. Its frequency response spans from 500 Hz to 20 kHz, with a self-resonant frequency of 500 Hz. The acoustic efficiency is specified at 82 dBA when tested at 1 W/10 cm. The unit has a diameter of 28.00 mm (1.102 inches) and a maximum installation height of 5.00 mm (0.197 inches). It employs wire lead termination and offers top porting.

Feature Summary

• Compact circular design suitable for space-constrained applications
• High-efficiency acoustic output utilizing neodymium magnet technology
• Broad frequency response extending into the upper audio spectrum
• Durable construction with polyester cone material

Applications

• Consumer electronic devices requiring compact audio output
• Portable communication equipment
• Medical instrumentation audio indicators
• Industrial control panel signaling

Procurement Notes

Verify the specific suffix L152 to confirm wire lead termination and top port configuration. Ensure the application environment remains within the operational temperature limits defined in the official datasheet. Confirm RoHS3 compliance requirements match project specifications. Cross-reference the manufacturer part number CLS0281-L152 against current distributor listings to ensure component authenticity and availability status before finalizing procurement plans.

Selection Notes

Select this component when a wide frequency range up to 20 kHz is required in a small form factor. The 8-ohm impedance matches standard amplifier outputs. Consider the 5 mm height constraint for enclosure design. Compare sensitivity ratings against alternative models if higher volume output is needed without increasing power input. Verify mounting hole patterns align with chassis designs.

Part Context

This model belongs to the CLS series of miniature speakers from Same Sky. The series focuses on providing high-quality audio solutions in reduced physical dimensions. The CLS0281 variant specifically addresses needs for broader bandwidth compared to lower-frequency limited counterparts. It represents a balance between acoustic performance and physical size constraints typical in modern portable electronics.

Replacement Considerations

CLS0282MA-L152: Offers extended high-frequency response up to 10 kHz but lower sensitivity at 85 dBA. CLS0261MAE-L152: Smaller 26 mm diameter with narrower frequency range. CLS0231MA-1-L152: Smallest 23 mm option with highest sensitivity but limited low-frequency extension.
