The component operates with a supply voltage of 1.3 V and presents an impedance of 2.2 kOhms. This specific model is part of the broader microphone product line, engineered to deliver precise sound capture in compact form factors suitable for integrated electronic systems.

Microphones Feature Summary

• Omnidirectional polar pattern for uniform sound pickup from all directions
• Analog output signal configuration
• Boom-style mechanical design for flexible positioning

Microphones Applications

• Voice input devices
• Communication equipment
• Audio recording interfaces

Microphones Procurement Notes

Verify the exact datasheet version before integration, as specifications may vary between manufacturing batches. Confirm that the 1.3 V operating voltage aligns with your system's power rails. Ensure the 2.2 kOhm impedance is compatible with your preamplifier input stage to prevent signal degradation or loading issues during final assembly.

Microphones Selection Notes

Select this component when an omnidirectional response is required for ambient voice capture rather than directional isolation. The analog interface necessitates appropriate conditioning circuitry compared to digital alternatives. Consider the physical dimensions of the boom style to ensure it fits within the designated enclosure space without interfering with other mechanical components.

Microphones Part Context

This microphone belongs to Knowles' portfolio of precision acoustic sensors. The company utilizes rigorous testing protocols to ensure reliability across its product range. The FB-MU series represents their analog microphone offerings, distinguished by specific polar patterns and output types tailored for various consumer and industrial audio applications.

Microphones Replacement Considerations

Direct substitutes must match the omnidirectional pattern, analog output type, and similar electrical characteristics such as 1.3 V operation and 2.2 kOhm impedance. Verify mechanical compatibility with existing mounting structures. Cross-reference with Knowles' official substitution guides for approved equivalent models.
