POM-5238L

Microphones Overview

The POM-5238L is an electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional polar pattern and provides analog output. The device operates with a sensitivity of -38dB ±3dB and covers a frequency range from 20 Hz to 15 kHz. Physical dimensions include a diameter of 6.00 mm (0.236 inches) and a maximum height of 5.40 mm (0.213 inches). The component utilizes solder pad termination for circuit integration.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Electret condenser transducer technology
• Analog signal output capability

Microphones Applications

• General purpose audio sensing
• Voice recognition input devices
• Consumer electronic audio modules

Microphones Procurement Notes

Verify the specific suffix designation when ordering, as the base model POM-5238L is listed as obsolete in some catalogs while POM-5238L-R indicates RoHS3 compliance. Confirm current availability status directly with authorized distributors or the manufacturer, as stock levels fluctuate. Ensure the required termination type matches the target PCB layout before finalizing procurement.

Microphones Selection Notes

Select this component for applications requiring a standard-sized, omnidirectional electret microphone with analog output. Consider the physical constraints of the 6mm diameter and 5.4mm height profile during mechanical design. Verify that the system power supply and biasing requirements align with standard electret operation characteristics. Check for RoHS compliance needs, as the R-suffix variant explicitly meets these standards.

Microphones Part Context

This part belongs to the POM series of microphones from PUI Audio, Inc., which focuses on compact audio solutions. The POM-5238L represents a legacy product line, with newer compliant variants like the POM-5238L-R available. It serves as a fundamental acoustic input component for various consumer electronics and industrial audio interfaces.

Microphones Replacement Considerations

The POM-5238L-R is a confirmed substitute offering RoHS3 compliance. Verify pinout compatibility and electrical parameter equivalence before substitution. Other generic 6mm electret microphones may require circuit adjustments due to differing sensitivity or impedance values.
