EK-23089-C37

Microphones Overview

The EK-23089-C37 is an omnidirectional electret condenser microphone from Knowles, designed for high-fidelity audio capture. It features a sensitivity of -57dB ±2dB referenced at 1V/Pa (74dB SPL) and operates within a frequency range of 100 Hz to 10 kHz. The component utilizes analog output and requires a supply voltage between 0.9V and 10V DC. Its rugged construction supports severe environmental conditions, while the low-noise profile aligns with the capabilities of the EK series.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound pickup
• Rugged construction engineered to withstand severe environmental conditions
• Low noise performance characteristic of the EK series

Microphones Applications

• Voice recording devices requiring low noise floors
• Portable audio equipment
• Environmental monitoring systems

Microphones Procurement Notes

Verify the specific suffix C37 against official Knowles documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing circuit biasing requirements given the wide operating voltage range. Confirm RoHS compliance status through current manufacturer declarations prior to integration into regulated products.

Microphones Selection Notes

Select this model when omnidirectional coverage is required alongside robust physical durability. The -57dB sensitivity offers a balance for general voice applications without excessive gain requirements. Consider the 100Hz lower frequency limit for applications where deep bass response is not critical.

Microphones Part Context

This component belongs to the EK series, which represents Knowles' lowest noise microphone offerings. The series emphasizes reliability in harsh environments while maintaining high signal integrity. The EK-23089-C37 variant specifically targets applications needing standard omnidirectional response with analog output capabilities.
