TO-24611-D60

Overview

The Knowles TO-24611-D60 is an analog omnidirectional electret condenser microphone designed for voice applications. It operates within a frequency range of 100 Hz to 5.8 kHz and requires a supply voltage between 0.9 V and 1.6 V. The device features a sensitivity of -56 dB ±3 dB at 74 dB SPL, ensuring reliable audio capture in standard acoustic environments. It utilizes solder pad termination for surface-mount integration and measures 3.57 mm x 3.57 mm x 2.28 mm.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound reception from all directions
• Electret condenser transducer technology for stable analog audio output
• Low-voltage operation capability suitable for portable battery-powered devices

Applications

• Voice recognition systems
• Consumer electronic audio input modules
• Portable communication devices

Procurement Notes

Verify the specific suffix designation (D60) against official Knowles documentation to confirm exact sensitivity and frequency response tolerances. Ensure compatibility with existing PCB footprint dimensions and soldering thermal profiles. Confirm RoHS compliance status through current manufacturer certificates prior to final procurement authorization.

Selection Notes

Select this component when an omnidirectional response is required for general voice capture rather than directional noise rejection. The low operating voltage range makes it appropriate for systems powered by single-cell batteries or low-voltage regulators. Evaluate the sensitivity specification against the target signal-to-noise ratio requirements of the application circuit.

Part Context

This model belongs to the Knowles TO series of miniature microphones, which are widely used in compact consumer electronics. The series emphasizes small form factors and reliable performance in voice-centric applications. The TO-24611 variant specifically targets surface-mount assembly processes common in modern automated manufacturing lines.

Replacement Considerations

The TO-24611-000 is documented as a similar replacement option within the same manufacturer portfolio. Verify mechanical footprint compatibility and electrical parameter alignment before substituting.
