Microphones Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm port configuration and sensitivity tolerances. Ensure the procurement channel provides original packaging documentation to guarantee component authenticity and traceability. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing orders.

Microphones Selection Notes

Select this component when a low-profile omnidirectional microphone is required for analog audio interfaces. The 4.4 kOhm impedance and 1.3 V bias requirement must align with the host circuit's preamplifier specifications. Consider the 100 Hz to 5 kHz bandwidth limitation if high-fidelity wideband audio recording is necessary.

Microphones Part Context

This part belongs to the EK series of omnidirectional microphones from Knowles. The series emphasizes a balance between physical dimensions and acoustic performance. The EK-23032-000 variant specifically utilizes a three-port configuration as indicated by its model designation, distinguishing it from other variants in the same family.
