ROM-2244P-NF-R

Microphones Overview

The ROM-2244P-NF-R is an analog omnidirectional electret condenser microphone manufactured by PUI Audio. It features a sensitivity of -44 dB with a tolerance of ±3 dB and operates within a frequency range of 30 Hz to 15 kHz. The device requires a supply voltage between 2 V and 10 V and presents an impedance of 2.2 kOhm. It utilizes PC pins for termination and has a diameter of 0.228 inches.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Electret condenser transducer technology for stable analog signal output
• PC pin termination style designed for through-hole printed circuit board mounting

Microphones Applications

• Consumer electronics audio input devices
• Industrial control panel voice communication systems
• Medical equipment user interface microphones

Microphones Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required impedance and sensitivity tolerances. Confirm that the PC pin spacing matches the target PCB footprint design. Ensure the operating voltage range aligns with the system power supply specifications before integration.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general ambient sound capture rather than directional focusing. The low impedance value facilitates easy interfacing with standard preamplifier circuits. Consider the physical diameter constraints and through-hole mounting requirements during the mechanical layout phase.

Microphones Part Context

This microphone belongs to the ROM series of analog audio components produced by PUI Audio, Inc., a manufacturer specializing in audio solutions for industrial and consumer markets. The series provides standardized electret condenser options for various enclosure sizes and mounting styles.

Microphones Replacement Considerations

Cross-reference alternative part numbers only if they explicitly match the 2.2 kOhm impedance, -44 dB sensitivity, and 0.228-inch diameter specifications documented in official substitution lists.
