FG-26107-D65

Microphones Overview

The Knowles FG-26107-D65 is a miniature omnidirectional electret condenser microphone designed for analog audio signal capture. It operates within a frequency range of 100 Hz to 10 kHz and features a sensitivity of -53.5 dB ±1 dB at 94 dB SPL. The device requires a supply voltage of 1.3 V and draws a supply current of 50 µA. It utilizes a 4.4 kOhm impedance and employs a solder pad termination method. The physical dimensions are approximately 2.5 mm in diameter with a maximum height of 4.13 mm, housed in a circular package suitable for surface-mount applications.

Microphones Procurement Notes

Verify the specific suffix designation against official Knowles documentation to ensure correct acoustic and electrical characteristics. Confirm RoHS compliance status as historical data indicates potential non-compliance for certain variants. Validate that the solder pad termination matches the target PCB layout requirements before finalizing procurement orders.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for analog audio input. Ensure the design accommodates the 1.3 V operating voltage and 50 µA current draw. Verify that the 100 Hz to 10 kHz frequency response aligns with the application's speech or narrowband audio requirements rather than wideband music reproduction.

Microphones Part Context

This part belongs to the FG series of miniature microphones manufactured by Knowles. The series is characterized by small footprint designs intended for integration into compact consumer electronic devices. The specific model variant denotes particular manufacturing tolerances and packaging configurations within this product line.

Microphones Replacement Considerations
