TO-30043-000

Overview

The Knowles TO-30043-000 is an analog electret condenser microphone featuring omnidirectional polar characteristics. It operates within a frequency range of 70 Hz to 5.7 kHz and delivers a sensitivity of -54 dB ±3 dB at 74 dB SPL. The device utilizes wire leads for connection and functions with a supply voltage of 1.6 V.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Electret condenser transducer technology
• Analog output signal generation

Applications

• General purpose audio recording
• Voice communication devices
• Consumer electronics audio input

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical dimensions. Ensure compatibility with existing biasing circuits, as the component requires a 1.6 V operating voltage. Confirm lead type and length requirements against the target assembly design before procurement.

Selection Notes

Select this component when an omnidirectional response is required for ambient sound capture. The fixed sensitivity and frequency range suit standard voice applications rather than high-fidelity music reproduction. Verify that the wire lead termination method aligns with the printed circuit board layout constraints.

Part Context

This microphone belongs to the Knowles Acoustics portfolio, which specializes in compact audio transducers. The product line includes various form factors designed for integration into portable and stationary electronic devices requiring reliable analog audio input capabilities.

Replacement Considerations

Cross-reference with other Knowles electret microphones sharing identical sensitivity and voltage specifications. Ensure any substitute maintains the same omnidirectional characteristic and physical mounting interface to preserve acoustic performance.
