Microphones Procurement Notes

Verify the specific revision suffix and packaging configuration against the manufacturer's latest documentation before ordering. Ensure that the input voltage and biasing requirements align with the system design specifications to maintain optimal signal-to-noise performance. Confirm RoHS compliance status if required by regional regulations.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for space-constrained designs. The 1.3 V operating voltage makes it suitable for battery-powered applications. Consider the 4.4 kOhm impedance when designing the preamplifier interface to ensure proper signal transfer and minimal noise introduction.

Microphones Part Context

This model belongs to the Knowles EM series of electret condenser microphones. These components are engineered for high reliability and consistent acoustic performance in mass-produced electronics. The C36 suffix typically denotes specific packaging or terminal configurations within the product line.

Microphones Replacement Considerations

Cross-reference with EM-23369-C36 for similar form factor but verify sensitivity differences (-52 dB vs unspecified). Check EM-23056-C36 for potential pin-compatible alternatives. Always validate electrical parameters and mechanical dimensions against the original design requirements.
