Microphones Procurement Notes

Verify component authenticity through authorized Knowles distributors or certified suppliers. Confirm RoHS compliance status prior to integration. Ensure storage conditions meet manufacturer specifications to preserve acoustic performance. Validate part markings against official datasheet identifiers to prevent counterfeit substitution.

Microphones Selection Notes

Select this model when low voltage operation and small form factor are critical. The 1.3 V supply requirement suits battery-powered portable devices. Consider the 4.4 kOhm impedance for proper preamplifier matching. Evaluate the -53 dBA sensitivity against ambient noise requirements in the target application environment.

Microphones Part Context

This component belongs to the Knowles FG-23652 series of miniature microphones. The series utilizes electret condenser technology optimized for high-volume consumer electronics. Similar variants include the FG-23652-P16 and FG-23653-C36, which share core acoustic characteristics but differ in termination methods and packaging configurations.

Microphones Replacement Considerations

Direct substitutes within the same family include the FG-23652-P16. Verify pinout compatibility and mechanical footprint alignment before replacement. Cross-reference electrical parameters such as sensitivity and impedance to ensure circuit functionality remains unchanged during substitution.
