Procurement Notes

Verify the specific datasheet version when ordering, as conflicting specifications exist in public records regarding rated power (0.3 W vs 1.3 W) and sensitivity. Confirm physical mounting requirements and soldering compatibility with your PCB design before finalizing procurement. Ensure the supplier provides official documentation from BeStar Technologies to validate the exact electrical parameters for your integration needs.

Selection Notes

Select this component for applications requiring a compact, round form factor with standard 32 Ohm impedance. It is suitable for low-power audio indication tasks where a frequency response centered around 1–4 kHz is sufficient. Consider the physical depth of 16.5 mm when designing enclosure constraints. Verify thermal operating ranges if the device will be used in high-temperature automotive environments.
