FB-DE-30290-000

Microphones Overview

The Knowles FB-DE-30290-000 is a noise-canceling microphone featuring wire leads for termination. It has a side port location and measures 0.315 inches (8.00mm) in diameter with a maximum height of 0.210 inches (5.33mm). The component includes a 140mm long wire lead assembly.

Microphones Feature Summary

• Noise canceling directional capability
• Side port acoustic design
• Wire lead termination style

Microphones Applications

• Voice recognition systems requiring noise reduction
• Hands-free communication devices
• Consumer electronics with spatial audio constraints

Microphones Procurement Notes

Verify the specific wire length and termination type against system requirements. Confirm that the side port orientation aligns with the acoustic enclosure design. Ensure compatibility with existing harnesses due to the fixed 140mm lead length. Check mechanical clearance for the 8.00mm diameter housing during integration.

Microphones Selection Notes

Select this component when directional noise cancellation is required alongside flexible wiring connections. The side port configuration suits applications where top-mounted ports are obstructed. Consider the physical dimensions and wire length as primary constraints for enclosure layout and cable management strategies.

Microphones Part Context

This model belongs to the Knowles FB series of electret microphones designed for consumer audio applications. The DE suffix typically denotes specific wire lead configurations within the product family, distinguishing it from surface-mount or other termination variants.

Microphones Replacement Considerations

Direct substitutes include the FB-DE-30291-000, which shares similar form factors but may differ in wire specifications. Verify acoustic performance curves and electrical characteristics before swapping to ensure functional equivalence in noise-canceling applications.
