Procurement Notes
Verify the specific acoustic performance requirements against the 70.50 dBA efficiency rating at 1W/1M. Confirm that the 8-ohm impedance matches the amplifier output stage. Ensure the physical dimensions of 16.00 mm by 9.00 mm fit the enclosure constraints. Check datasheet specifications for thermal limits and mounting requirements before finalizing the component selection.
Selection Notes
Select this component for applications requiring a compact, rectangular speaker with standard 8-ohm impedance. The 400 Hz to 20 kHz frequency range suits general voice and tone reproduction. Consider the top port orientation for acoustic coupling. Evaluate the 850 Hz self-resonant frequency for potential impact on low-frequency response in the target system design.
Part Context
This part belongs to the Knowles speaker portfolio, utilizing magnetic technology for sound generation. It is categorized as a general-purpose receiver or speaker element. The product line focuses on providing reliable audio transducers for various electronic assemblies where space efficiency and standard electrical characteristics are required.
Replacement Considerations
Direct substitutes must match the 8-ohm impedance, rectangular 16x9 mm footprint, and top port configuration. Verify frequency response compatibility within the 400 Hz to 20 kHz range. Ensure equivalent efficiency ratings to maintain system volume levels without amplifier modification.
