TO-30034-000

Overview

The Knowles TO-30034-000 is an analog electret condenser microphone designed for omnidirectional sound pickup. It operates within a frequency range of 500 Hz to 2 kHz and features a sensitivity of -54dB ±3dB at 94dB SPL. The component requires a rated voltage of 1.3 V and draws a current of 75uA. Its impedance is specified as 3.75kΩ. Physically, the microphone measures 7.65mm in length and 3.58mm in width, utilizing solder pads for surface mount integration.

Feature Summary

• Omnidirectional acoustic pattern for uniform sound capture
• Electret condenser technology for analog signal output
• Matched set configuration ensuring consistent performance across units

Applications

• Voice recognition systems requiring specific frequency band response
• Consumer audio devices with limited power budgets
• Industrial communication equipment needing robust analog microphones

Procurement Notes

Verify the specific revision of the datasheet to confirm RoHS compliance status and exact dimensional tolerances before finalizing design integration. Ensure that the supply chain documentation explicitly lists the part number TO-30034-000 to avoid substitution errors with similar Knowles models. Cross-reference the manufacturer's official ordering information to validate active product status and availability constraints.

Selection Notes

Select this component when a matched set of omnidirectional microphones is required for applications demanding precise sensitivity matching. The low operating voltage and current make it suitable for battery-powered devices. Engineers should consider the specific 500 Hz to 2 kHz frequency response limitation when evaluating suitability for wideband audio applications versus voice-centric use cases.

Part Context

This microphone belongs to Knowles' portfolio of precision audio components, specifically targeting the analog electret condenser segment. It is engineered for high-volume manufacturing environments where consistency between individual units is critical. The part represents a specialized solution for OEMs integrating compact audio sensing capabilities into consumer electronics and industrial hardware.

Replacement Considerations
