Microphones Procurement Notes

Verify the specific revision code and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure that the soldering profile matches the component's thermal specifications to maintain reliability. Confirm availability through official channels as distribution status may vary by region.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for space-constrained PCB layouts. The 1.3 V operating voltage suits battery-powered portable devices. Consider the 12 kOhm impedance and -55 dBA sensitivity when designing the pre-amplifier stage to ensure optimal signal-to-noise ratio.

Microphones Part Context

This part belongs to the Knowles FG series of microphones, which are engineered for high performance in small form factors. The series utilizes advanced electret condenser technology to provide consistent audio quality across various consumer and industrial applications.

Microphones Replacement Considerations

Check for direct substitutes within the same FG series family that share identical pinout and dimensional constraints. Verify that any replacement maintains the same sensitivity, impedance, and voltage requirements to avoid circuit redesign.
