Microphones Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Knowles or authorized distributors before finalizing procurement. Confirm that the operating voltage range aligns with the target system power rails. Ensure mechanical mounting pads match the PCB layout dimensions specified in the official package drawing.

Microphones Selection Notes

Select this component when high miniaturization is required alongside standard analog audio performance. The fixed sensitivity and voltage requirements must be compatible with the host circuit's biasing network. Consider the 100 Hz lower frequency limit when evaluating low-frequency sound capture needs compared to broader bandwidth alternatives.

Microphones Part Context

This model belongs to Knowles' portfolio of subminiature microphones, leveraging their expertise in balanced armature and electret technologies. These components are engineered specifically for applications demanding reliable audio capture in extremely small enclosures, such as hearing aids and specialized medical instruments.

Microphones Replacement Considerations

Cross-reference with other Knowles models in the EM series for dimensional compatibility. Verify that substitute parts maintain the same -52 dB sensitivity and 0.9 V minimum operating voltage to ensure circuit functionality without modification.
