Microphones Procurement Notes

Verify the specific suffix C37 against official Knowles documentation to confirm pinout configuration and sensitivity tolerances. Ensure that the procurement channel provides genuine components with traceable manufacturing dates to prevent counterfeit risks. Cross-reference the datasheet revision history for any updates to mechanical drawings or electrical specifications before finalizing orders.

Microphones Selection Notes

Select this component when an omnidirectional response is required in compact form factors. The wide voltage tolerance allows compatibility with various biasing circuits. Consider the 5.7 kHz upper frequency limit for applications not requiring extended high-frequency audio reproduction. Verify mechanical clearance constraints against the specified 2.21 mm height dimension during PCB layout.
