EM-23456-C36

Microphones Overview

The Knowles EM-23456-C36 is an electret condenser microphone designed for analog audio applications. It features an omnidirectional polar pattern and operates within a frequency range of 100 Hz to 5.4 kHz. The device requires a rated voltage of 1.3 V, with a supply range of 0.9 V to 10 V and a typical supply current of 50 µA. Sensitivity is specified as -56 dB ±3 dB at 74 dB SPL. It utilizes solder pad termination and has a bottom port location.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Electret condenser technology for analog signal output
• Low power consumption suitable for battery-operated devices

Microphones Applications

• General purpose audio recording
• Voice recognition systems
• Consumer electronic devices requiring analog microphone input

Microphones Procurement Notes

Verify the specific datasheet version and sensitivity tolerance (-56 dB ±3 dB) against project requirements. Confirm that the 50 µA supply current fits the system's power budget. Ensure the bottom port orientation aligns with the mechanical enclosure design to prevent acoustic obstruction during integration.

Microphones Selection Notes

Select this component when an omnidirectional analog electret microphone is required. Consider the 100 Hz to 5.4 kHz frequency response limitations for voice-centric applications rather than high-fidelity music. Verify compatibility with the target circuit's biasing voltage (0.9 V to 10 V range) and interface impedance requirements.

Microphones Part Context

This model belongs to Knowles' portfolio of electret condenser microphones. It is distinct from MEMS or digital microphone variants. The part is categorized under audio products and is currently listed as active in distribution channels.

Microphones Replacement Considerations

The EM-23056-C36 and EM-23346-C36 are related models within the same product family. Cross-reference specifications carefully, as dimensional tolerances and electrical characteristics may vary between these specific part numbers.
