Microphones Procurement Notes

Verify the specific datasheet version corresponding to the EK-23103-000 part number before procurement. Confirm that the required operating voltage range of 0.9 V to 10 V aligns with your system design. Ensure compatibility with the specified sensitivity of -53 dB ±2 dB for your audio chain requirements. Check for any RoHS compliance documentation if mandated by your manufacturing standards.

Microphones Selection Notes

Select this component when an omnidirectional electret condenser microphone is needed for space-constrained designs. The wide supply voltage range offers flexibility in power management. Consider the -53 dB sensitivity level against your noise floor requirements. Verify that the 100 Hz to 8 kHz frequency response meets the intended voice or audio bandwidth needs without additional filtering.

Microphones Part Context

This component belongs to the Knowles EK series of microphones, which are widely used in consumer electronics. The EK-23103-000 specifically denotes an analog electret condenser type. It is distinct from digital MEMS microphones or other polar patterns within the same manufacturer's portfolio. The series is known for providing reliable acoustic performance in small form factors.

Microphones Replacement Considerations

Direct replacements must match the electrical characteristics and mechanical footprint. Verify equivalent sensitivity and frequency response ranges. Ensure the replacement supports the same supply voltage limits. Consult official substitution lists from Knowles for validated alternatives.
