Procurement Notes
Verify the exact acoustic specifications and mechanical dimensions against the official Knowles datasheet before finalizing the design. Ensure the 51-ohm impedance aligns with the target amplifier or driver circuit requirements. Confirm that the end-port configuration meets the enclosure's acoustic venting needs. Cross-reference the package details to guarantee physical compatibility with the printed circuit board layout.
Selection Notes
Select this model when a low-profile receiver speaker with a specific 51-ohm impedance is required. The integrated port design makes it suitable for applications where traditional back-loaded designs are not feasible due to size limitations. Consider the acoustic power handling and frequency response characteristics relative to the intended voice or music playback requirements.
Part Context
This component belongs to the Knowles speaker and transducer product line, which specializes in miniaturized audio solutions. The CI series typically targets mobile and wearable technology markets, focusing on high reliability and precise acoustic tuning within minimal volume constraints compared to standard loudspeaker formats.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with any alternative components by matching impedance, physical footprint, and mounting interface specifications.
