Speakers Procurement Notes

Verify the specific impedance rating (140 Ohms) against circuit requirements before procurement. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure mechanical dimensions match the PCB footprint and housing constraints. Cross-reference datasheet revisions to guarantee compatibility with existing assembly processes.

Speakers Selection Notes

Select this component when high fidelity and low distortion are critical in small form factors. The 140 Ohm impedance suits specific driver circuits requiring higher resistance loads. Consider the 200 Hz to 6.1 kHz bandwidth for voice or mid-range audio emphasis. Evaluate the top-port orientation relative to acoustic chamber design.

Speakers Part Context

This part belongs to Knowles' line of balanced armature speakers, engineered for premium audio devices. It represents a specialized solution for hearing aid manufacturers seeking reliable, miniaturized transducers. The product series emphasizes acoustic clarity and mechanical stability in tight spaces.

Speakers Replacement Considerations

Check for direct substitutes with identical 140 Ohm impedance and similar frequency response curves. Verify mechanical compatibility including mounting holes and port alignment. Ensure replacement parts maintain equivalent sound pressure levels for consistent user experience.
