Microphones Procurement Notes
Verify the specific datasheet version from Knowles or authorized distributors to confirm pinout configurations and mechanical drawings. Ensure that the procurement channel provides genuine components with valid RoHS compliance documentation. Cross-reference the part number against official manufacturer catalogs to avoid counterfeit substitutions.
Microphones Selection Notes
Select this component when an omnidirectional response is required for general-purpose analog audio capture. Consider the 100 Hz to 10 kHz frequency range suitability for voice-centric applications rather than full-range music reproduction. Evaluate the 2.28 mm depth constraint against available board real estate during the mechanical design phase.
Microphones Part Context
This microphone belongs to Knowles' portfolio of electret condenser microphones, which are widely used in consumer electronics. The EM series typically focuses on providing reliable acoustic performance in compact packages. This specific model emphasizes omnidirectional characteristics, distinguishing it from directional variants within the same product family.
Microphones Replacement Considerations
Consult official Knowles documentation for direct cross-references. Verify compatibility of mounting dimensions and electrical characteristics before substituting with other omnidirectional electret microphones.
