Microphones Procurement Notes

Verify the specific suffix code to ensure correct sensitivity and impedance variants. Confirm RoHS compliance status through official datasheets before integration. Check for recent product change notifications regarding material or process updates. Ensure ESD handling procedures are followed during assembly due to the sensitive internal MEMS structure.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for analog signal processing. Compare sensitivity and impedance against preamplifier input requirements. Consider the operating voltage range and current draw relative to system power budgets. Evaluate mechanical mounting constraints given the small SMD footprint.

Microphones Part Context

This model belongs to the Knowles EM series of subminiature electret microphones. These components are engineered for high reliability in consumer electronics. The series offers various size options to accommodate different design constraints while maintaining consistent acoustic performance standards across the product line.

Microphones Replacement Considerations

Cross-reference with EM-23368-C36 for similar dimensional profiles but verify impedance differences. Check EM-23368-C54 for potential pin-compatible alternatives within the same family. Confirm functional equivalence through detailed parameter comparison rather than assuming interchangeability.
