AUM-5247L

Overview

The AUM-5247L is a unidirectional electret condenser microphone manufactured by PUI Audio. It features an SMD/SMT termination type and operates at a supply voltage of 1.5 V. The device has a sensitivity of -47 dB and an impedance of 680 Ohms. Its physical dimensions are 9.7 mm in diameter, 9.7 mm in length, and 5.2 mm in depth.

Feature Summary

• Unidirectional acoustic design for focused sound capture
• Surface-mount technology (SMD/SMT) compatible construction
• Low operating voltage requirement of 1.5 V

Applications

• Voice recognition systems
• Consumer audio recording devices
• Communication equipment requiring directional pickup

Procurement Notes

Verify component availability as the AUM-5247L is listed as obsolete or discontinued by the manufacturer. Confirm current stock status with authorized distributors before finalizing procurement plans. Ensure that any substitute components meet the original electrical and mechanical specifications to maintain system integrity.

Selection Notes

Select this component when a low-profile, unidirectional microphone is required for surface-mount assembly. The 680 Ohm impedance and -47 dB sensitivity suit applications needing moderate gain. Verify that the 1.5 V operating voltage aligns with the target circuit's power supply constraints.

Part Context

This part belongs to the AUM series of microphones from PUI Audio. It is designed for compact electronic assemblies where space is limited. The unidirectional characteristic distinguishes it from omnidirectional variants within the same product family.
