Microphones Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required termination styles and environmental ratings. Confirm that the operating voltage aligns with the 2 V to 10 V specification during system integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and technical documentation availability before finalizing procurement orders.

Microphones Selection Notes

Select this component when an omnidirectional analog microphone is required for compact audio applications. The 6 mm diameter and 2.7 mm height suit space-constrained designs. Ensure the circuit supports the specified 500 µA bias current and 2.2 kohm impedance. This model is suitable for environments where broad directional pickup is preferred over focused sound acquisition.

Microphones Part Context

The POM-2744P belongs to the POM series of microphones from PUI Audio, Inc., which focuses on compact analog electret condenser solutions. This series provides standardized form factors for easy integration into various electronic devices. The part represents a standard configuration within the product line, offering reliable performance for general audio sensing tasks.

Microphones Replacement Considerations

The POM-2744P-C33-R is a documented variant within the same family. Verify if the suffix indicates differences in termination or packaging that affect mechanical fit. Direct substitution requires confirming identical electrical parameters and physical dimensions.
