FG-26163-000

Microphones Overview

The FG-26163-000 is an analog electret condenser microphone manufactured by Knowles. It features an omnidirectional polar pattern and operates at a supply voltage of 1.3V with a typical supply current of 50µA. The device provides a sensitivity of -53.5dB ±3dB referenced to 74dB SPL. It utilizes solder pads for termination and has a circular physical form factor with a diameter of 2.59mm (0.101 inches) and a height range of 0.9mm to 1.6mm. The acoustic interface design supports operation within specific frequency ranges.

Microphones Feature Summary

• Omnidirectional acoustic response for uniform sound capture
• Low power consumption suitable for battery-operated devices
• Solder pad termination for direct board integration

Microphones Applications

• Acoustic interface modules
• General purpose audio sensing
• Embedded voice recognition systems

Microphones Procurement Notes

Verify the specific revision code and manufacturing date code upon order confirmation, as Knowles reserves the right to change designs and specifications without prior notice. Ensure that the procurement documentation explicitly confirms the 1.3V operating voltage and the -53.5dB sensitivity tolerance to match system requirements. Cross-reference the terminal type to confirm solder pad availability rather than wire leads.

Microphones Selection Notes

Select this component when an omnidirectional electret condenser microphone is required for low-voltage applications. The 1.3V supply requirement limits its use in higher voltage systems unless level shifting is implemented. Consider the physical dimensions of 2.59mm diameter and up to 1.6mm height for enclosure constraints. The solder pad termination method requires compatible surface mount or through-hole soldering processes depending on the PCB layout.

Microphones Part Context

This model belongs to the Knowles FG series of analog microphones. It is distinct from the company's MEMS microphone lines, such as the MM60, which are designed for AI-optimized hearing aids. Unlike the pulse power capacitors or balanced armature drivers also produced by Knowles, this component is strictly an acoustic transducer element intended for signal acquisition rather than audio output or energy storage.

Microphones Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Knowles directly for equivalent models with matching sensitivity and voltage specifications.
