Microphones Procurement Notes

Verify the specific datasheet version for the PNM-2751L-C3310-R to confirm current manufacturing status and environmental compliance details. Ensure that the 2V operating voltage requirement aligns with the target system power supply design. Confirm that the solder pin termination method matches the intended PCB assembly process before finalizing procurement orders.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general sound capture applications. The -51 dB sensitivity rating indicates its output level relative to input pressure. Consider the 2V operating voltage constraint during system power budgeting. Verify that the physical dimensions and solder pin configuration fit within the available space on the printed circuit board layout.

Microphones Part Context

This part belongs to the PUI Audio microphone product line, categorized under audio devices. It is distinct from MEMS microphones and piezoelectric buzzer elements offered by the same manufacturer. The model number identifies a specific electret capsule variant designed for low-cost, high-volume audio sensing applications requiring simple biasing circuits.

Microphones Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching electrical parameters such as -51 dB sensitivity, 2V operation, and 2.2 kOhm impedance.
