EK-23132-C36

Microphones Overview

The Knowles EK-23132-C36 is an omnidirectional electret condenser microphone designed for analog audio applications. It features a rectangular surface-mount package measuring 5.56 mm in length, 3.98 mm in width, and 2.21 mm in depth. The device operates at a supply voltage of 1.3 VDC with a current rating of 50 µA. It exhibits a sensitivity of -54 dBA and an impedance of 3.5 kOhms. The frequency response spans from 100 Hz to 10 kHz, supporting high-frequency atmospheric pressure recording.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern suitable for ambient sound capture
• Electret condenser transducer technology for analog signal output
• Compact rectangular surface-mount form factor for space-constrained integration

Microphones Applications

• High-frequency Martian atmospheric dynamics and wind speed analysis
• Microphone array beamforming systems requiring balanced line-level outputs
• Automated environmental monitoring stations

Microphones Procurement Notes

Verify the specific suffix C36 against official Knowles documentation to confirm port configuration and sensitivity tolerances. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check component obsolescence status as some variants may be discontinued. Ensure supply chain sources provide authentic manufacturer data sheets rather than generic distributor summaries.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional electret microphone is required for precise acoustic sensing. The 1.3 VDC operating voltage suits low-power embedded designs. Verify that the 100 Hz to 10 kHz bandwidth aligns with target frequency requirements. Consider the 3.5 kOhm impedance for proper preamplifier interface matching.
