Procurement Notes
Verify the specific revision level and manufacturing date code upon order confirmation. Ensure compatibility with the intended PCB footprint dimensions of 7.87mm x 5.59mm. Confirm that the top port orientation aligns with the acoustic design requirements of the final assembly. Check for any specific handling instructions regarding magnetic sensitivity during assembly.
Selection Notes
Select this component when a low-profile magnetic microphone with solder pad termination is required. The top port configuration suits applications where acoustic exposure from the upper surface is necessary. Verify that the operating environment does not interfere with the magnetic properties or the solder joint integrity during thermal processing.
Part Context
This model belongs to the Knowles magnetic microphone series, which provides compact solutions for various audio sensing needs. The BJ-23141-134 specifically addresses the need for small form factor components in modern electronics. It complements other models in the lineup that may offer different port locations or termination styles.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Ensure replacement parts match the magnetic type, solder pad termination, and dimensional constraints of 0.310" L x 0.220" W. Verify acoustic performance equivalence if direct pin-to-pin substitution is not available.
