Microphones Procurement Notes

Verify the specific datasheet revision to confirm mechanical dimensions and electrical tolerances match your design requirements. Ensure the operating voltage range of 1.3 V to 10 V aligns with your system power supply. Confirm that the analog output interface is compatible with your downstream signal processing components before finalizing procurement.

Microphones Selection Notes

Select this component when analog noise-cancelling performance is required for voice-centric applications. The wide operating voltage range offers flexibility in power supply design. Consider the 300 Hz to 4 kHz frequency response suitability for human speech clarity. Verify mechanical fitment constraints regarding the 8 mm diameter and wire lead configuration during the initial design phase.

Microphones Part Context

This part belongs to the Knowles PNR series of boom microphones, which includes various directional and omnidirectional elements. The series supports different gooseneck styles and diameters. This specific model focuses on analog noise-cancelling performance, distinguishing it from digital or non-cancelling variants within the broader product family.

Microphones Replacement Considerations

Consult official Knowles documentation for verified substitute part numbers. Cross-referencing requires matching analog output type, noise-cancelling specifications, and physical mounting dimensions. Generic replacements may not replicate the specific -60 dB noise cancellation performance or frequency response characteristics.
