POM-5038L-C3310-R

Microphones Overview

The POM-5038L-C3310-R is an omnidirectional electret condenser microphone manufactured by PUI Audio, Inc. It features a frequency response range of 20 Hz to 20 kHz and operates within a supply voltage of 1 VDC to 10 VDC. The device has a sensitivity of -38 dB and a maximum current consumption of 500 µA. Its impedance is specified as 680 ohms. The microphone utilizes solder pad termination and has a maximum height of 0.213 inches (5.40 mm).

Microphones Feature Summary

• Omnidirectional polar pattern captures sound equally from all directions.
• Electret condenser transducer technology for audio signal conversion.
• Top port location design for acoustic intake.

Microphones Applications

• Conference phone systems
• Voice recording devices
• Audio input modules

Microphones Procurement Notes

Verify the specific suffix 'L' in the part number against official PUI Audio documentation to confirm the 680 ohm impedance specification. Ensure that the required operating voltage range of 1 VDC to 10 VDC aligns with the target circuit design before procurement. Cross-reference the physical dimensions, specifically the 5.40 mm maximum height, with the mechanical constraints of the intended assembly.

Microphones Selection Notes

Select this component when a compact, omnidirectional microphone is required for applications needing uniform sound capture from all angles. The low current consumption of 500 µA makes it suitable for battery-powered devices. The wide operating voltage range provides flexibility in power supply design. Consider the top-port configuration if the acoustic environment requires unobstructed frontal sound access.

Microphones Part Context

This model belongs to the POM series of omnidirectional electret condenser microphones from PUI Audio. It shares similar form factors and functional principles with other variants in the series, such as the POM-5038P-C3310-R, which differs primarily in impedance characteristics. The series is designed for general-purpose audio pickup applications requiring reliable performance in a small footprint.
