Speakers Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Knowles or authorized distributors before integration. Confirm that the 281 Ohm impedance and 100 Hz–5.5 kHz frequency response align with your acoustic design requirements. Ensure the rectangular SMT package footprint matches your PCB layout constraints. Check for any recent supply chain restrictions or alternative part recommendations from the manufacturer.

Speakers Selection Notes

Select this component when a compact, high-efficiency receiver is required for hearing aid or similar medical audio applications. The balanced armature design offers superior stability compared to dynamic drivers in small form factors. Consider the 281 Ohm impedance for matching amplifier output stages. The top-port configuration may influence acoustic chamber design. Evaluate the rectangular package dimensions against available board space.
