PMO-6022PN-48KDQ

Microphones Overview

The PMO-6022PN-48KDQ is an analog electret condenser microphone manufactured by Mallory Sonalert Products Inc. It features an omnidirectional polar pattern and operates within a frequency range of 100 Hz to 10 kHz. The device has a sensitivity of -48 dB ±2 dB at 94 dB SPL, referenced to 1 V/Pa with RL = 2.2 kΩ and Vcc = 2.0V. Maximum impedance is 2.2 kΩ at 1 kHz. Physical dimensions are 6.0 mm x 2.2 mm, utilizing PC pins for termination.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture from all directions
• Electret condenser transducer technology for stable analog signal output
• Compact surface-mount compatible form factor with PC pin termination

Microphones Applications

• Embedded audio sensing systems
• Voice recognition input modules
• Industrial noise monitoring devices

Microphones Procurement Notes

Verify the specific suffix KDQ against official Mallory Sonalert documentation to confirm exact sensitivity tolerance and impedance specifications. Ensure compatibility with required supply voltage (2.0V) and load resistance (2.2kΩ) during integration. Confirm physical footprint alignment with PCB layout constraints due to the 6.0x2.2mm dimension.

Microphones Selection Notes

Select this component when an omnidirectional response is required for ambient sound detection in compact embedded designs. The fixed sensitivity and impedance characteristics suit applications where consistent analog voltage output is critical. Evaluate the 100Hz-10kHz bandwidth against target acoustic frequencies to ensure adequate coverage for intended voice or tone detection tasks.

Microphones Part Context

This part belongs to the Mallory Sonalert product line specializing in audio transducers. Unlike their piezoelectric buzzers, this model is an electret microphone designed for input rather than output. It serves as a sensor component in electronic assemblies requiring acoustic data acquisition.

Microphones Replacement Considerations

No public substitute part numbers are documented in the provided source material. Cross-reference with other Mallory Sonalert microphones such as the PMO-4530PN-47UQ only if dimensional and electrical parameters match requirements.
