POM-2738P

Microphones Overview

The POM-2738P is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a 6 mm diameter circular housing with PC pin termination for through-hole mounting. The device operates on a rated voltage of 3 V, supporting a range up to 10 V, and draws a supply current of 500 µA. Key electrical specifications include a nominal impedance of 2.2 kOhms and a sensitivity of -38 dB.

Microphones Feature Summary

• Omnidirectional acoustic pattern for uniform sound capture from all directions
• Electret condenser technology providing analog audio output
• PC pin termination designed for standard through-hole PCB assembly

Microphones Applications

• Consumer electronic audio input devices
• Voice recognition systems
• General purpose sound detection circuits

Microphones Procurement Notes

Verify the specific suffix designation when ordering, as variants such as POM-2738P-R or POM-2738L-R may exist with different packaging or lead times. Confirm that the required termination type matches the target PCB layout, as surface mount options differ from the standard PC pins. Ensure the operating voltage aligns with the system's power supply constraints.

Microphones Selection Notes

Select this component for applications requiring a compact, low-power omnidirectional microphone with through-hole compatibility. The 2.2 kOhm impedance is compatible with standard preamplifier inputs. Consider the physical dimensions of the 6 mm housing to ensure adequate clearance within the final enclosure design.

Microphones Part Context

This part belongs to the POM series of microphones from PUI Audio, which are widely used in consumer electronics. The series offers various configurations including different diameters and termination styles. The POM-2738P specifically represents the 6 mm form factor with PC pin leads, distinguishing it from surface mount or smaller diameter alternatives in the same product line.

Microphones Replacement Considerations

Direct replacements include POM-2738P-R and POM-2738L-R, which share identical electrical characteristics but may differ in packaging or manufacturing lot specifications. Verify mechanical fit before substituting.
