AUM-5047L-3-R

Overview

The AUM-5047L-3-R is a unidirectional electret condenser microphone manufactured by PUI Audio. It features an SMD/SMT termination type and operates on a supply voltage of 1.5 VDC to 2 VDC. The device has a sensitivity of -46 dB and an impedance of 2.2 kOhms. Its physical dimensions are 9.7 mm in diameter, with a length of 6 mm, width of 6 mm, and depth of 5.2 mm.

Feature Summary

• Unidirectional acoustic design for focused sound capture
• Surface-mount technology (SMD/SMT) compatible construction
• Low voltage operation suitable for portable electronics

Applications

• Consumer electronics audio input
• Industrial control systems
• Security and fire alarm devices

Procurement Notes

Verify the specific datasheet version for the AUM-5047L-3-R to confirm current RoHS compliance status and exact electrical tolerances. Ensure that the PCB footprint matches the manufacturer's recommended land pattern for reliable SMD soldering. Confirm availability through authorized distributors as stock levels may vary.

Selection Notes

Select this component when a low-profile, unidirectional microphone is required for space-constrained designs. The 2.2 kOhm impedance and -46 dB sensitivity are standard for general voice pickup applications. Compare against the AUM-5047L-4-R if different impedance characteristics are needed, noting that the latter is listed as End of Life.

Part Context

This part belongs to the AUM series of microphones from PUI Audio, which specializes in audio components for medical, industrial, and consumer markets. The series includes various directional and omnidirectional options with different form factors and electrical specifications tailored for diverse integration needs.

Replacement Considerations

The AUM-5047L-4-R is a related model but is marked as End of Life. Verify compatibility with the AUM-5047L-3-LW100-R if lead wire termination is acceptable instead of surface mount.
