EM-6027LR-45

Microphones Overview

The EM-6027LR-45 is an analog electret condenser microphone manufactured by Soberton Inc. It features an omnidirectional polar pattern and operates within a frequency range of 50 Hz to 10 kHz. The device has a sensitivity of -45dB ±3dB at 94dB SPL and a signal-to-noise ratio of 58dB. Electrical specifications include a supply current of 500 µA, an impedance of 2.2 kOhms, and a voltage range of 1 V to 10 V. The physical dimensions are 6.00 mm in diameter and 2.90 mm in height.

Microphones Feature Summary

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

Microphones Applications

• Consumer electronics audio input
• Voice recognition systems
• General purpose sound detection

Microphones Procurement Notes

Verify the specific suffix LR-45 to confirm the -45dB sensitivity variant. Ensure compatibility with existing biasing circuits given the 500 µA supply current requirement. Confirm package type matches the leaded specification found in distributor listings. Check RoHS compliance status if required by local regulations.

Microphones Selection Notes

Select this component when an omnidirectional response is required for general audio pickup. The 2.2 kOhm impedance and 500 µA current draw suit standard interface circuits. Consider the 50 Hz lower frequency limit; applications requiring deeper bass response may need alternative models. Verify that the 10 kHz upper limit meets the target bandwidth requirements.

Microphones Part Context

This part belongs to the EM series of microphones from Soberton Inc. The series includes various sensitivity and frequency response variants. The EM-6027LR-45 specifically denotes the -45dB sensitivity version with the defined 50 Hz to 10 kHz operational range.

Microphones Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other EM-series parts from Soberton Inc. or comparable omnidirectional electret microphones with similar -45dB sensitivity and 2.2 kOhm impedance.
