Microphones Procurement Notes
Verify the specific datasheet version for the EM-24346-C48 to confirm exact mechanical tolerances and electrical characteristics prior to design-in. Ensure compatibility with existing biasing circuits given the 1.3 V operating requirement. Confirm RoHS compliance status matches project specifications. Validate that the SMD package dimensions fit the intended PCB layout constraints.
Microphones Selection Notes
Select this component when a miniature, high-performance microphone is required for behind-the-ear or in-the-ear hearing assistance devices. The low power consumption and small form factor make it suitable for battery-operated personal audio equipment where space is limited. Consider the omnidirectional pattern if uniform sound pickup from all angles is necessary for the application.
Microphones Part Context
This microphone belongs to Knowles' specialized line of audio transducers engineered specifically for hearing healthcare solutions. The EM series focuses on miniaturization and acoustic performance tailored for medical-grade personal audio devices. These components are integral to modern digital hearing aid architectures requiring precise sound capture.
Microphones Replacement Considerations
Consult official Knowles documentation for qualified alternative part numbers within the EM series. Verify that any substitute maintains identical acoustic performance, electrical parameters, and physical footprint to ensure seamless integration without redesigning the host device circuitry or housing.
