AOW-4544L-C3310-B-R

Overview

The AOW-4544L-C3310-B-R is an omnidirectional electret condenser microphone manufactured by PUI Audio. It operates on a supply voltage of 2 VDC and draws a current of 500 µA. The device features a sensitivity of -44 dB and an impedance of 2.2 kOhms. Its frequency response spans from 50 Hz to 16 kHz. The component utilizes surface-mount termination and has an IP57 rating for environmental protection.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Surface-mount solder pin termination
• IP57 environmental sealing

Applications

• Consumer electronics audio input
• Industrial control panels
• Medical devices
• Security systems

Procurement Notes

Verify the specific suffix 'L' against the manufacturer's part numbering system to confirm lead frame or plating specifications, as variations may exist within the AOW series. Confirm RoHS compliance status through the official datasheet before integration. Ensure the 2 VDC operating voltage aligns with the target circuit design constraints.

Selection Notes

Select this component when a low-profile, surface-mount microphone with moderate sensitivity is required. The 2.2 kOhm impedance matches standard preamplifier inputs. The IP57 rating makes it suitable for applications requiring resistance to dust and water immersion, distinguishing it from non-sealed variants in the same family.

Part Context

This microphone belongs to the AOW series of omnidirectional electret condenser microphones from PUI Audio. The series offers various termination styles and housing options. The AOW-4544L-C3310-B-R specifically denotes the surface-mount version with defined electrical characteristics and environmental sealing capabilities.

Replacement Considerations

The AOW-4544P-C3310-B-R is a related variant in the same series. Verify if the pin configuration and mounting footprint are identical before substitution, as package differences may exist between the 'L' and 'P' suffixes.
