AOM-4546L-R

Overview

The AOM-4546L-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a cylindrical design with a diameter of 9.7 mm and a total length of 9.7 mm, including a depth of 4.5 mm for the housing. The component operates at a supply voltage of 1.5 V and presents an impedance of 2.2 kOhms. Its sensitivity is rated at -46 dB. The device utilizes surface mount (SMD/SMT) termination for PCB integration and is supplied in bulk packaging.

Feature Summary

• Omnidirectional acoustic pickup pattern suitable for ambient sound capture
• Surface mount soldering configuration for automated assembly processes
• Low voltage operation compatible with standard biasing circuits

Applications

• Consumer electronic audio input devices
• Portable communication equipment
• General purpose voice detection modules

Procurement Notes

Verify the specific suffix designation against the manufacturer's current part numbering system to ensure correct termination type and environmental rating. Confirm RoHS compliance status through official documentation prior to finalizing procurement specifications. Cross-reference the Mouser part number 665-AOM4546LR for accurate distributor identification and technical datasheet access.

Selection Notes

Select this component when a low-profile, surface-mount omnidirectional microphone is required for compact circuit designs. The 2.2 kOhm impedance and -46 dB sensitivity define the electrical interface requirements for preamplifier stages. Ensure the PCB footprint matches the SMD package dimensions provided in the official mechanical drawings.
