AUM-5241L-HD

Overview

The PUI Audio AUM-5241L-HD is an electret condenser microphone designed for surface-mount applications. It features a unidirectional polar pattern and operates within a frequency range of 20 Hz to 20 kHz. The device requires a supply voltage between 1 VDC and 10 VDC, with a maximum operating current of 500 µA. Key electrical specifications include a sensitivity of -41 dB and an impedance of 3.3 kohms. The physical dimensions are 14 mm in diameter and 5.56 mm in height.

Feature Summary

• Surface-mount construction for automated assembly integration
• Wide operating supply voltage range from 1 VDC to 10 VDC
• High acoustic overload point of 135 dB for robust signal handling

Applications

• Consumer electronics requiring compact audio input
• Industrial control systems needing reliable voice recognition
• Medical devices with strict size constraints

Procurement Notes

Verify the specific revision of the datasheet to confirm RoHS compliance status and exact pinout configuration. Ensure that the PCB footprint matches the manufacturer's recommended land pattern to prevent soldering defects. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference the part number suffixes if alternative versions exist within the HD series.

Selection Notes

Select this component when a wide supply voltage tolerance is required, accommodating both low-voltage portable devices and higher-voltage industrial systems. The high acoustic overload point makes it suitable for environments with significant background noise or loud sound sources. Consider the 14 mm diameter constraint against available board space requirements.

Part Context

This model belongs to the AUM HD series of microphones from PUI Audio. The series is characterized by high durability and broad operational parameters compared to standard electret microphones. It serves as a specialized solution for applications demanding reliability under varying electrical conditions.

Replacement Considerations

Direct substitutes may include other unidirectional SMD electret microphones with similar 14 mm diameters. Verify that replacement parts support the 1 VDC to 10 VDC operating range and match the 3.3 kohm impedance specification to ensure circuit compatibility.
