• Medical device alert systems

Speakers Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct impedance and power ratings. Confirm that the solder eyelet termination style matches your printed circuit board layout requirements. Check RoHS compliance documentation for regulatory adherence in target markets.

Speakers Selection Notes

Select this component when a compact rectangular form factor is required over standard circular speakers. Ensure the application environment does not exceed the thermal limits associated with the 1.5 W power rating. Validate that the 8-ohm impedance aligns with the driving amplifier's output capabilities for optimal efficiency.

Speakers Part Context

This model belongs to Same Sky's miniature speaker series, designed for integration into portable and embedded electronic devices. The brand transition from CUI Devices maintains continuity in technical specifications and manufacturing standards for legacy and new designs.

Speakers Replacement Considerations

Cross-reference with other rectangular speakers in the 40x20mm footprint. Verify that substitute parts match the 8-ohm impedance and 1.5 W power handling to maintain system performance integrity.
