EK-23027

Microphones Overview

The Knowles EK-23027 is an omnidirectional analog electret condenser microphone designed for surface-mount technology (SMT) integration. It features a rectangular footprint measuring 5.56 mm in length, 3.98 mm in width, and 2.21 mm in height. The device operates within a voltage range of 1.3 V to 10 V with a supply current of 50 µA. It exhibits a sensitivity of -53 dBA and maintains an impedance of 4.4 kOhms. The frequency response spans from 100 Hz to 10 kHz, ensuring accurate audio capture across standard voice bands.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound pickup from all directions
• Analog output signal generation via integrated preamplifier circuitry
• Compact surface-mount package optimized for space-constrained PCB layouts

Microphones Applications

• Voice recognition systems requiring consistent directional response
• Consumer electronic devices with limited internal volume
• Portable audio recording equipment

Microphones Procurement Notes

Verify the specific suffix code (e.g., C36) against official datasheets to confirm port configuration and sensitivity tolerances. Ensure compatibility with SMT reflow profiles and check RoHS compliance status prior to integration. Confirm availability through authorized distributors as lead times may vary by manufacturing batch.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for analog audio interfaces. The fixed 4.4 kOhm impedance and 50 µA current draw suit battery-powered applications. Validate that the operating voltage range aligns with the system power supply rails before finalizing the design.

Microphones Part Context

This model belongs to the EK series of microphones manufactured by Knowles. The series is characterized by high-performance electret condenser elements packaged for automated surface-mount assembly. These components are engineered for reliability in consumer electronics and industrial audio applications.

Microphones Replacement Considerations
