Microphones Procurement Notes

Verify the specific suffix designation against official documentation to confirm exact termination style and packaging configuration. Confirm RoHS compliance status through current manufacturer declarations. Ensure the selected variant matches the required operating voltage and sensitivity specifications for the target application circuit.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for compact audio designs. The 2 V operating voltage suits battery-powered systems. Verify that the 2.2 kOhm impedance aligns with the preamplifier input requirements. Consider the physical depth constraint of 1.3 mm for enclosure fitment.

Microphones Part Context

This part belongs to the POM series of microphones from PUI Audio. The series includes various configurations differing in termination type, such as surface mount or through-hole options, and dimensional variations. The POM-3546L specifically denotes the 6 mm diameter variant with solder pin termination.

Microphones Replacement Considerations

POM-3546P-R offers similar electrical characteristics but uses SMD/SMT termination instead of solder pins.
