• Portable communication equipment

Microphones Procurement Notes

Verify the specific suffix C36 against official Knowles documentation to confirm the exact port orientation and sensitivity tolerance. Ensure compatibility with the target operating voltage range of 1.3 V to 10 V. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Microphones Selection Notes

Select this component when a compact, surface-mount omnidirectional microphone is required for voice applications. The 4.4 kOhm impedance and low supply current make it suitable for battery-powered designs. Verify that the 100 Hz to 10 kHz frequency response aligns with the specific audio bandwidth requirements of the application.

Microphones Part Context

This part belongs to the EK series of microphones from Knowles, which are designed for general-purpose audio sensing. The EK series typically offers various packaging and porting options to accommodate different mechanical constraints in consumer electronics and industrial audio modules.

Microphones Replacement Considerations

EK-23027-C04 shares similar electrical characteristics but differs in port location. Cross-referencing with EK-26695-C36 is necessary as it has comparable sensitivity but distinct dimensional and impedance specifications.
