Microphones Procurement Notes

Verify the specific datasheet version to confirm the operating supply voltage, as sources indicate both 1.3 VDC and 10 VDC specifications for this part number. Ensure the physical footprint matches the 3.57 x 3.57 mm dimensions. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement.

Microphones Selection Notes

Select this component when a subminiature form factor is required for hearing aid or similar medical/audio applications. The high operating voltage specification distinguishes it from standard low-voltage MEMS microphones. Verify that the 5.5 kOhm impedance aligns with the input requirements of the connected preamplifier circuit.

Microphones Part Context

This microphone belongs to the Knowles subminiature microphone portfolio, designed for space-constrained wearable and medical devices. The EM series typically targets hearing aids and personal audio equipment where size and power efficiency are critical constraints.
