Microphones Procurement Notes

Verify the specific suffix C36 against official Knowles documentation to confirm terminal configuration and port orientation. Ensure compatibility with the required 1.3 VDC operating voltage and 50 µA bias current during circuit design. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Microphones Selection Notes

Select this component when an omnidirectional response is required within a strict 5.56 x 3.98 mm envelope. The -54 dBA sensitivity and 3.5 kOhm impedance define the interface requirements for the preamplifier stage. Verify that the screw termination style aligns with the intended assembly process and board layout constraints.

Microphones Part Context

This microphone belongs to the EK series manufactured by Knowles, which specializes in miniature audio transducers. The EK series provides various form factors and sensitivity levels tailored for portable electronics and industrial applications. This specific model represents a standard omnidirectional variant within that product line.

Microphones Replacement Considerations

EK-23132-C36 shares similar dimensions but differs in sensitivity (-53 dB) and impedance (4.4 kOhms). Cross-reference electrical parameters carefully as these differences affect circuit gain and biasing requirements.
