MB6022ASC-1L

Microphones Overview

The Knowles MB6022ASC-1L is an omnidirectional analog electret condenser microphone with a 6.00 mm diameter and 2.40 mm height. It operates on a 2 V to 10 V supply with 500 µA current consumption. The device features a sensitivity of -42dB ±3dB @ 94dB SPL, a frequency range of 100 Hz to 10 kHz, and an impedance of 2.2 kOhms. It utilizes top porting and pad termination.

Microphones Feature Summary

• Omnidirectional acoustic pattern for uniform sound capture
• Analog output signal generation via electret condenser technology
• Top-port design allowing flexible mounting orientations

Microphones Applications

• Voice recognition systems
• Consumer audio recording devices
• Telecommunication handsets

Microphones Procurement Notes

Verify the specific suffix against official Knowles documentation to confirm exact electrical tolerances and mechanical dimensions. Confirm component availability status as older series may be discontinued or subject to last-time buy constraints. Ensure compatibility with existing PCB footprints and soldering profiles.

Microphones Selection Notes

Select this model when a compact, low-power omnidirectional microphone is required for voice-band applications. Consider the 2.2 kOhm impedance and -42dB sensitivity for pre-amplifier matching. Verify that the 100 Hz to 10 kHz frequency response meets the target application's audio fidelity requirements.

Microphones Part Context

This component belongs to the MD series of miniature microphones from Knowles. It shares dimensional similarities with other models in the family but differs in specific electrical characteristics and termination types. The series is designed for integration into space-constrained electronic devices requiring reliable acoustic transduction.

Microphones Replacement Considerations

The MD6022ASC-0 is a documented alternative within the same product line. Verify pinout compatibility and sensitivity specifications before substitution. Ensure the replacement part meets the same environmental and mechanical testing standards required by the original design.
