EK-23024-C37

Microphones Overview

The Knowles EK-23024-C37 is an omnidirectional electret condenser microphone designed for analog audio signal capture. It features a sensitivity of -53 dB ±1 dB at 94 dB SPL and operates within a frequency range of 100 Hz to 6 kHz. The component measures 5.56 mm in length, 3.98 mm in width, and 2.21 mm in depth. It utilizes surface-mount device (SMD/SMT) solder pads for termination and requires a supply voltage of 10 V with a current consumption of 50 µA.

Microphones Feature Summary

• Omnidirectional acoustic design for wide-angle sound capture
• Integrated RFI suppression for improved signal integrity
• Compact surface-mount form factor suitable for space-constrained PCBs

Microphones Applications

• Voice recognition systems
• Consumer electronic devices
• Telecommunication equipment

Microphones Procurement Notes

Verify the specific suffix code against official Knowles documentation to confirm exact sensitivity tolerances and port configurations. Ensure compatibility with existing PCB footprints and biasing circuits before integration. Cross-reference datasheet revisions to confirm RoHS compliance status and material declarations.

Microphones Selection Notes

Select this component when omnidirectional pickup patterns are required for voice-centric applications. The fixed 10V bias requirement and 50µA current draw must align with system power budgets. Evaluate the 100Hz to 6kHz frequency response against target audio bandwidth needs to ensure adequate speech intelligibility without unnecessary high-frequency noise capture.

Microphones Part Context

This model belongs to the EK/EY series of microphones from Knowles Acoustics. These components are engineered as compact, high-performance solutions for modern portable electronics. The series emphasizes miniaturization while maintaining reliable analog output characteristics for embedded audio processing tasks.

Microphones Replacement Considerations

EK-23024-C04 shares identical physical dimensions and general specifications but may differ in specific manufacturing lot parameters or minor tolerance variations. Verify electrical equivalence through direct datasheet comparison before substitution.
