Microphones Procurement Notes

Verify the specific sensitivity rating of -65 dB and confirm the JA/JK port configuration matches your acoustic requirements. Ensure the screw terminal interface is compatible with your assembly process. Cross-reference the physical dimensions of 4.0 x 5.59 x 2.28 mm against your enclosure constraints before finalizing procurement.

Microphones Selection Notes

Select this component when omnidirectional coverage combined with active noise reduction is required. The screw terminal option suits applications where robust mechanical connections are preferred over soldering. Consider the compact form factor for tight spatial constraints in portable or embedded audio systems.

Microphones Part Context

This microphone belongs to Knowles' portfolio of electret condenser microphones designed for high-fidelity audio applications. It complements other models by offering specialized noise cancellation features while maintaining a standard omnidirectional response curve suitable for general voice and ambient sound capture tasks.
