POM-3546P-R

Microphones Overview

The POM-3546P-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a 6 mm diameter and operates at a voltage of 1.5 V. The device has an impedance of 2.2 kOhms and a sensitivity of -38 dB. Physical dimensions include a length of 9.7 mm, width of 9.7 mm, and depth of 6.7 mm. It utilizes SMD/SMT termination for surface mount assembly.

Microphones Feature Summary

• Omnidirectional acoustic response for uniform sound capture from all directions
• Surface mount design facilitates automated PCB assembly processes
• Compact cylindrical form factor suitable for space-constrained electronic enclosures

Microphones Applications

• Consumer electronics audio input modules
• Portable communication devices
• Voice recognition systems

Microphones Procurement Notes

Verify the specific termination type against the target PCB footprint, as this model uses SMD/SMT contacts. Confirm that the 1.5 V operating voltage aligns with the system power supply rails. Ensure the 2.2 kOhm impedance matches the preamplifier input requirements for optimal signal transfer.

Microphones Selection Notes

Select this component when a low-profile, surface-mount microphone is required for general voice pickup. Compare sensitivity levels against alternative models if higher gain is needed. Verify mechanical clearance constraints regarding the 9.7 mm height dimension during the layout phase.

Microphones Part Context

This part belongs to the POM series of microphones from PUI Audio. The series includes various configurations differing in termination style, such as through-hole pins or different lead lengths. This specific variant is distinguished by its surface mount pads and standard 6 mm housing size.

Microphones Replacement Considerations

Direct substitutes within the same series may include POM-3546L-R, though it utilizes solder pin termination instead of surface mount pads. Verify dimensional compatibility and electrical parameter equivalence before swapping components.
