Overview
The AOM-6545P-R is an omnidirectional electret microphone manufactured by PUI Audio. It features a cylindrical design with a diameter of 9.4 mm and a length of 9.7 mm. The component operates at a voltage of 1.5 V and provides a sensitivity of -45 dB. Its nominal impedance is specified as 2.2 kOhms, although some listings indicate 1.0 kOhm. The device utilizes solder pin termination for board mounting.
Feature Summary
- Omnidirectional acoustic response for uniform sound capture from all directions
- Compact cylindrical housing suitable for space-constrained electronic assemblies
- Low voltage operation compatible with standard portable device power supplies
Applications
- Consumer electronics audio input modules
- Portable recording devices
- Voice recognition systems
Procurement Notes
Verify the specific suffix (e.g., -R) when ordering to ensure correct packaging and compliance status. Confirm impedance requirements against circuit design specifications, as values may vary between 1.0 kOhm and 2.2 kOhms in different documentation sources. Check RoHS compliance details directly with the manufacturer or distributor before finalizing procurement.
Selection Notes
Select this model for applications requiring a standard-sized omnidirectional microphone with low power consumption. Ensure the PCB layout accommodates the 9.4 mm diameter and 9.7 mm height dimensions. Verify that the target circuit can support the 1.5 V operating voltage and matches the microphone's impedance characteristics for optimal signal transfer.
Part Context
This component belongs to the AOM series of microphones from PUI Audio. The series includes various sizes and sensitivities designed for general audio pickup applications. The AOM-6545P-R variant specifically denotes the 9.4 mm diameter version within this product line.
Replacement Considerations
The AOM-4544P-NF-R is a similar omnidirectional microphone with comparable dimensions and electrical characteristics. Verify impedance and sensitivity differences before substitution.
