Procurement Notes

Verify the specific datasheet version when sourcing, as documentation indicates potential variations in frequency range specifications between sources. Confirm that the package type matches project requirements, noting that official documentation lists tray packaging while distributors may offer cut tape options. Ensure the operating temperature range of -20°C to 60°C aligns with the final assembly environment constraints.

Selection Notes

Select this component for applications requiring a compact rectangular speaker with standard 16 Ohm impedance. The 85 dBA sensitivity provides adequate output for general audio tasks. Consider the physical dimensions and wire lead configuration during PCB layout or enclosure design to ensure proper fit and electrical connectivity without requiring additional adapters.
