TM-24546-C36

Overview

The Knowles TM-24546-C36 is a subminiature omnidirectional electret condenser microphone designed for high-performance audio capture in space-constrained environments. It operates on a DC supply voltage of 1.3 V with a current drain of 50 uA. The device features a frequency range of 100 Hz to 6.4 kHz and an impedance of 4.4 kOhms. Sensitivity is rated at -54.5 dB ±3dB @ 74dB SPL. Physical dimensions are approximately 3.57 mm x 3.57 mm x 1.77 mm, facilitating integration into compact electronic assemblies.

Feature Summary

Omnidirectional acoustic design for consistent sound capture from all angles
Subminiature form factor suitable for tight spatial constraints
Low power consumption operation compatible with portable battery-powered devices

Applications

Hearing aid repair and replacement
Compact consumer electronics audio input
Instrumentation requiring clear audio capture

Procurement Notes

Verify the specific suffix C36 against the manufacturer's latest documentation to ensure correct sensitivity and impedance specifications. Confirm that the operating voltage requirements align with the target circuit design, as variations may exist within the product family. Ensure compatibility with existing mounting structures given the precise physical dimensions.

Selection Notes

Select this component when space is limited and omnidirectional pickup is required. The low operating voltage makes it suitable for battery-operated applications. Verify that the frequency response meets the specific audio bandwidth needs of the application, particularly regarding the upper limit of 6.4 kHz.

Part Context

This microphone belongs to Knowles' subminiature electret condenser series, engineered for rugged environments and high-performance audio. It is part of a broader family of compact microphones used in hearing aids and small electronic devices where size and power efficiency are critical constraints.
