Overview
The Knowles TO-30079-000 is an omnidirectional electret condenser microphone designed for analog audio applications. It is supplied as a matched set to ensure consistent performance across multiple channels or units. The component operates within a frequency range of 500 Hz to 2 kHz, making it suitable for voice-centric communication systems where clarity in the mid-range spectrum is prioritized over wideband fidelity.
Feature Summary
- Omnidirectional pickup pattern for uniform sound capture from all directions
- Supplied as a matched set to maintain acoustic consistency across assemblies
- Electret condenser technology providing stable analog output signals
Applications
- Voice communication devices requiring consistent multi-unit matching
- Analog audio input systems with focused mid-range frequency requirements
- Consumer electronics utilizing omnidirectional microphone arrays
Procurement Notes
Verify that the specific procurement lot corresponds to the matched set configuration rather than individual units. Confirm the analog output type compatibility with the target circuit design. Ensure the packaging format aligns with automated assembly requirements if applicable. Cross-reference the manufacturer part number against official distributor catalogs to avoid substitution errors.
Selection Notes
Select this component when system design requires pre-matched acoustic characteristics to minimize calibration efforts. The limited frequency response suits applications where high-frequency noise rejection is beneficial. Consider the omnidirectional nature for environments without directional sound sources. Validate that the analog interface matches the downstream processing electronics.
Part Context
This microphone belongs to the Knowles TO series, which focuses on reliable electret condenser solutions. The TO-30079-000 variant specifically addresses needs for matched sets, distinguishing it from standard single-unit offerings. It represents a specialized solution for manufacturers prioritizing batch consistency in voice-grade audio hardware.
Replacement Considerations
Direct substitutes must match the matched set specification and omnidirectional characteristic. Verify frequency response alignment with the 500 Hz to 2 kHz range. Ensure the replacement maintains the same analog output behavior and physical form factor for board compatibility.
