PMOF-9745W-42DQ

Microphones Overview

The PMOF-9745W-42DQ 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 20 Hz to 16 kHz. The device requires a supply voltage between 1.1 V and 10 V. Its sensitivity is rated at -42 dB ±3 dB relative to 1 V/Pa, measured at 1 kHz with a load resistance of 2.2 kΩ. The maximum impedance is 2.2 kΩ at 1 kHz. The component utilizes wire leads for termination.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture from all directions
• Electret condenser transducer technology for analog audio output
• Wide operating voltage range supporting low-power applications

Microphones Applications

• Voice recognition systems requiring omnidirectional input
• Consumer electronic devices with limited power budgets
• Audio recording equipment needing broad frequency response

Microphones Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct lead type and sensitivity tolerance. Confirm RoHS compliance status through current manufacturer datasheets before integration. Cross-reference the part number with authorized distributors to validate active production status and avoid obsolete stock.

Microphones Selection Notes

Select this component when an omnidirectional response is required for voice-centric applications. The wide voltage range allows flexibility in circuit design across various battery-operated devices. Ensure the application environment does not exceed the specified frequency limits or require directional noise rejection capabilities.

Microphones Part Context

This model belongs to the PMOF series of analog microphones from Mallory Sonalert. The series typically includes various sensitivity levels and termination options. This specific variant uses wire leads rather than surface mount packaging, distinguishing it from other models in the same product family designed for automated assembly processes.

Microphones Replacement Considerations

Direct substitutes include PMOF-9745W-38DQ and PMOF-9745W-46DQ from the same manufacturer, which share identical physical dimensions and electrical interfaces but differ in sensitivity ratings.
