TM141067

Overview

The TM141067 is an analog electret condenser microphone manufactured by Top Shelf Acoustics, LLC. It features a unidirectional cardioid polar pattern and operates within a frequency range of 50 Hz to 10 kHz. The device requires a bias voltage between 1 V and 10 V for functionality. Its sensitivity is specified at -34 dB ±3 dB. The component utilizes solder pads for termination, facilitating direct integration into printed circuit boards without additional connectors.

Feature Summary

• Unidirectional cardioid acoustic design for focused sound capture
• Electret condenser transducer technology for analog audio output
• Direct solder pad termination for board-level assembly

Applications

• Voice communication systems requiring directional pickup
• Analog audio input interfaces
• Embedded microphone solutions for electronic devices

Procurement Notes

Verify the specific datasheet version from Top Shelf Acoustics, LLC to confirm electrical tolerances and mechanical dimensions. Ensure compatibility with existing bias voltage circuits operating between 1 V and 10 V. Confirm that the solder pad termination style matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a cardioid response is required to reject rear-arriving noise. The fixed sensitivity of -34 dB suits applications where moderate gain stages are available. Verify that the 50 Hz to 10 kHz bandwidth aligns with the intended voice or narrowband audio transmission needs rather than full-range music reproduction.

Part Context

This model belongs to the TM14 series of electret condenser microphones produced by Top Shelf Acoustics, LLC. The series includes variants with different polar patterns and sensitivity levels. The TM141067 specifically denotes the unidirectional configuration with standard sensitivity, distinct from noise-cancelling models in the same product family.

Replacement Considerations

Cross-reference with other TM14 series units if different sensitivity or polar patterns are needed. No direct public substitute part numbers are confirmed for identical performance specifications.
