TP-24605-000

Overview

The Knowles TP-24605-000 is a subminiature electret condenser microphone designed for high-performance audio capture in space-constrained environments. It operates within a frequency range of 100 Hz to 8.5 kHz and features unidirectional polar characteristics. The device requires a bias voltage between 0.9 V and 1.6 V, drawing a current of 100 uA. Sensitivity is rated at -59 dB ±3 dB relative to 1V/Pa at 74 dB SPL. It utilizes solder pad termination and has an impedance of 4.4 kOhm.

Feature Summary

• Compact subminiature form factor suitable for rugged and space-limited applications
• Unidirectional acoustic design for focused sound capture
• Analog output via direct solder pad termination

Applications

• Portable electronic devices requiring compact audio input
• Rugged environmental audio recording systems
• Consumer electronics with limited internal volume

Procurement Notes

Verify the specific datasheet version and RoHS compliance details directly from the manufacturer before integration. Confirm that the operating voltage range aligns with your system's power supply constraints. Ensure mechanical mounting provisions accommodate the subminiature package dimensions. Check for any recent product discontinuance notifications or end-of-life status updates.

Selection Notes

Select this component when a small footprint is critical alongside standard analog microphone performance. The fixed sensitivity and impedance values suit circuits designed for consistent gain stages. Consider the narrow frequency response if wideband audio fidelity is not required. Verify that the solder pad termination method matches your PCB assembly capabilities.

Part Context

This model belongs to the Knowles TP series of subminiature electret microphones. These components are engineered for durability and consistent acoustic performance in demanding conditions. The series targets markets where size reduction is prioritized without compromising basic audio quality standards.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter alignment before replacing. Ensure mechanical dimensions fit existing board layouts.
