AMM-3742-T-WP-R

Overview

The AMM-3742-T-WP-R is an omnidirectional MEMS microphone manufactured by PUI Audio. It features a sensitivity of -42 dB and operates at a supply voltage of 2 VDC. The device has an impedance of 300 ohms and meets IP57 standards for water and dust resistance. Its physical dimensions are 3.76 mm in length, 2.95 mm in width, and 1.2 mm in depth.

Feature Summary

• IP57 rated environmental protection against water and dust ingress
• Omnidirectional acoustic design for uniform sound capture
• MEMS technology ensuring consistent performance

Applications

• Consumer electronics requiring moisture resistance
• Wearable audio devices
• Smart home voice control units

Procurement Notes

Verify the specific suffix WP-R to confirm the inclusion of waterproofing capabilities and tape packaging format. Ensure compatibility with 2VDC operating voltages during integration. Confirm that the IP57 rating aligns with the target application's environmental exposure requirements before finalizing orders.

Selection Notes

Select this component when high sensitivity and robust environmental sealing are required. The 300-ohm impedance suits standard interface circuits. Consider the compact 3.76mm footprint for space-constrained designs. Validate that the analog output type matches the system's signal processing architecture.

Part Context

This part belongs to the AMM series of MEMS microphones from PUI Audio. It shares the core acoustic characteristics of the series but differs in packaging and environmental sealing specifications. The WP-R designation indicates specific handling and protection features distinct from standard reel or bulk variants.

Replacement Considerations

AMM-3742-2-T offers similar acoustic performance without the specified waterproofing.
