TM141028

Overview

The TM141028 is an omnidirectional analog electret condenser microphone manufactured by Top Shelf Acoustics, LLC. It operates within a frequency range of 50 Hz to 10 kHz and requires a supply voltage between 1 V and 10 V. The device features a sensitivity of -36dB ±3dB and utilizes solder pads for connection. Its physical dimensions include a diameter of 9.70mm (0.382 inches).

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions.
• Electret condenser transducer technology for analog audio signal generation.
• Direct solder pad termination for straightforward PCB integration.

Applications

• General purpose voice recording devices
• Consumer electronic audio input modules
• Industrial noise monitoring equipment

Procurement Notes

Verify the manufacturer designation as Top Shelf Acoustics, LLC, noting potential cross-references to Omron Electronics in some databases. Confirm RoHS compliance status and ensure the specific solder pad package matches your board layout requirements before finalizing orders.

Selection Notes

Select this component when an omnidirectional response is required for broad-spectrum audio capture. Ensure the circuit design supports the specified 1 V to 10 V operating voltage range. Consider the -36dB sensitivity level against ambient noise requirements for the intended application environment.

Part Context

This model belongs to the TM14 series of analog microphones. It shares similar electrical characteristics with other variants like the TM141061 but differs in polar pattern, offering omnidirectional coverage instead of noise-canceling directional properties.

Replacement Considerations

Cross-reference with TM141042 or TM141029 if alternative sourcing is needed, though functional equivalence must be verified against specific sensitivity and dimensional constraints.
