Microphones Procurement Notes

Verify the specific ordering suffix and packaging configuration directly with Knowles or authorized distributors, as availability may vary by region. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the selected variant matches the required termination style and sensitivity tolerance for your circuit design before placing orders.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional electret microphone is required for analog signal processing. The 4.4 kOhm impedance and -52 dBA sensitivity are key parameters for matching preamplifier stages. Consider the 1.3 VDC operating voltage and 50 uA current draw for power budget calculations in portable systems requiring high-fidelity voice capture.

Microphones Part Context

The EM-23368-C36 belongs to Knowles' subminiature electret microphone series, engineered for high-performance audio in rugged environments. It complements similar models like the EM-23369-C36 and EA-21867-C36, offering standardized dimensions and electrical characteristics for consistent integration across various audio input applications in modern electronic devices.

Microphones Replacement Considerations

Direct substitutes include the EM-23369-C36 and EA-21867-C36, which share similar omnidirectional characteristics and compact form factors. Verify impedance and sensitivity tolerances against these alternatives to ensure compatibility with existing circuit designs without requiring significant schematic modifications.
